Why is the screen black when I turn on my laptop?

How to fix a black screen on my HP laptop

Here are the solutions that helped people solve the problem. You don’t have to experience them all; just work with the list until everything works again.

  • Hard reset your laptop
  • Restart the explorer.exe process
  • Update your graphics drivers
  • Disable Fast Startup
  • Undo recent changes

Apart from fix 1. you must be logged into Windows on the problem laptop to try these solutions. If you are unable to log into Windows, turn your laptop on and off 3 times to perform a hard reboot and restart your computer in Safe Mode. and then try these solutions.

Fix 3: update graphics drivers

A missing or outdated graphics driver in your laptop can cause a black screen, so you should make sure the graphics drivers in your laptop are up to date and update those that are not up to date.

There are two ways to update your graphics drivers, manually and automatically.

You can manually find the latest version of your graphics driver from the manufacturer, download and install it on your computer. This takes time and computer skills. We recommend this if you are confident in your computer skills.

Why is my HP laptop screen black?

There are various reasons that can cause a black screen in your laptop. One of the common causes is hardware malfunction, such as a poor GPU connection or bad cables or port, which can also cause the screen to not work. Apart from a hardware issue, your laptop screen may be black due to software issues such as a virus or software corruption.

It is sometimes difficult to pinpoint the exact cause of the black screen problem, but there is still something you can do to fix the problem. You can first find out the cause of the problem by connecting the external monitor securely and correctly to your HP laptop.

Fix 1: hard reset your laptop

Usually, faulty hardware can cause a black screen on an HP laptop, so you should remove the connected hardware from the laptop and see what the problem is.

  • Turn off your laptop.
  • Disconnect power, hard drives, battery, and all connected peripherals.
  • Press and hold the power button for 60 seconds and release.
  • Insert the battery and connect the charger. Then don’t connect anything else.
  • Boot your laptop again to see if it works now.

If this fixes the black screen issue on your HP laptop, then you should have found and fixed the problem. Then you can shut down your laptop and plug in one peripheral once and see if the problem can be fixed. Then you can find the cause and fix it.

If your black screen is still there, don’t worry. We have other solutions to try. Please note, if you are unable to log into your Windows laptop, you need to boot your laptop into Safe Mode before trying the following solutions.

Fix 2: restart the explorer.exe process

If the explorer.exe process has been closed (possibly due to a virus), your HP laptop may go into a black screen.

The Explorer.exe process manages the desktop, taskbar, etc. on your laptop, so if closed on your system, your desktop and taskbar will become invisible and your screen will turn black.

Note. The screenshots below are from Windows 10 and the fixes also work on Windows 8 and Windows 7.

  • Press the Ctrl keys on your keyboard at the same time. Shift and Esc to bring up the task manager.
  • Click on the “Details” tab (or the “Processes” tab if you are using Windows 7).
  • Scroll down and find the explorer.exe process.
  • If yes, end the process by selecting explorer.exe and clicking End Task.
  • Restart your HP laptop and see if it fixes black screen issues.

If you cannot find explorer.exe in the list, you can start the process yourself:

  • While in Task Manager, click “File” and select “Run New Task”.
  • Type explorer.exe and press Enter on your keyboard.
  • The process will start and you can check if your desktop returns to normal.

Your HP laptop screen is black. and you haven’t done anything to cause the black screen problem? Do not panic! Black screen issues usually occur after Windows Update and many people have solved black screen on HP laptop with the solutions described in this article.

If you have problems like HP screen goes black but still works, or black screen on startup, you can try the methods below to fix your problem.

Black screen when I turn on the computer

In this article, I want to share with you my observations of the situation when we observe a black screen when the computer is turned on. We call this black screen when the computer is turned on. “Malevich’s painting” 🙂

Again, I will make a reservation that all the main points and breakdowns associated with a black screen when booting a computer, we have already analyzed in detail in the section of our website called “Repair your computer yourself”. We had separate articles related to hard drive problems, an article devoted to problems with RAM, an article called “motherboard burned out”, “how to reset BIOS settings” and a lot of other useful information on the topic of self-repairing a computer.

Be sure to read them for a full understanding of what the main malfunctions of computer equipment are, how they should be properly diagnosed and eliminated. Also pay attention to the article on computer power supplies (its last few paragraphs), which talks about insufficient capacity of old power supplies, which can lead to a black screen when the computer is turned on.

Below I want to share with you one more observation, why can you see a black screen when you start your computer? Both cases I had were connected with computers that were brought to me for repair (I still follow my home better) 🙂

In general, when diagnosing someone else’s computer, keep the following in your head: I do not know how this or that owner treats the equipment (what is the norm for some, may be completely unacceptable for others). For example, I had a case when the hostess of the house decorated her system unit with souvenir fridge magnets! Can you imagine what happened to the poor car ?! 🙂

So. let’s continue. I will describe two of my non-standard cases, when the computer was turned on with a black screen. In both cases, the reason was the same. adhesion of foreign matter (simply. dirt) to the tracks of the printed circuit board. Only in the first case it was the motherboard, and in the other. discrete graphics card. The result, as you can see, is the same. black screen when you turn on the computer.

According to one of the “unofficial” definitions: “dirt. This is any chemical compound that is in the wrong place” 🙂 I do not know what compounds that dirt on the motherboard consisted of, but after removing it with an alcohol solution, the computer started up normally and works to this day.

The second case, which led to the appearance of a black screen when the computer was booted, I even managed to photograph for you. Once we bought 10 old PCI video cards for terminal clients on the radio market for a department of pieces. They brought it in, started testing (substitute one at a time in the pre-assembled working configuration). Seven cards turned out to be working, three. not. I twirled the last of the non-working in my hands, mentally wondering at the sellers who sell faulty devices, and noticed a strange darkening in the corner.

Let’s enlarge the part of the image that interests us for clarity:

You can clearly see the adhering dirt on the PCB tracks. Remembering my previous successful experience with cleaning, I decided to follow the same procedure and find out if this particular substance causes a black screen when the computer is turned on.?

Said. done! There was a “mister muscle” at hand, took it, moistened a lint-free cloth and carefully removed all the dirt from the tracks. Here’s what I ended up with:

He let the card dry, inserted it into the computer, turned it on and. it all worked! 🙂 Now this video is successfully working on one of our terminal clients.

Conclusion: if you see a black screen when you turn on your computer (especially if this is not your computer), do not be too lazy to make sure that it is the owner. adequate people and do not fill their technique with sweet syrup (there was such a case) and handle it carefully.

How do I repair my computer myself? Let’s answer like this: attentiveness, attentiveness, and again. attentiveness! Here is the advice that will help you avoid losing your time and nerves if the computer does not work and you need to professionally diagnose its malfunction.

One of the options is RAM

Next, you need to try experimenting with RAM. There are often cases when, after a banal rearrangement of modules, the laptop was safely started.

Just unscrew a few screws on the bottom of the laptop and slide off the cover that blocks access to the RAM.

Removing and swapping laptop RAM

If you have 2 memory modules, remove both of them and try inserting them one at a time in different slots, each time trying to turn on the laptop.

If there is only one memory module, then just pull it out, wipe it with an ordinary eraser or, in extreme cases, with your hand, the contacts and insert into place.

Hard drive. as a possible reason for a black laptop screen when turned on

The next step in the event of a problem with a black laptop screen is to unplug the hard drive. There are times when the hard drive fails mechanically and the laptop, when turned on, unsuccessfully tries to identify it.

In most laptops, accessing the hard drive is as easy as accessing RAM. Only in the latest, usually budget models of 2016-2017, in order to get to the RAM and hard drive, you need to disassemble the entire laptop.

First thing to do

So, if the laptop does not show anything when you press the power button, then the first thing to start dealing with this problem is to remove the battery from it and after a few minutes try to turn it on directly from the outlet.

Black screen when turning on laptop

In this article, we will consider the situation when, when you turn on the laptop, nothing appears on the screen at all, no inscriptions and numbers, only the fan rotates and there is no reaction to keystrokes.

Most often, this situation means serious problems with the motherboard. But about everything in order.

Diagnostics using an external monitor

You can also try to connect the laptop to an external monitor to eliminate the likelihood of damage to the matrix cable and the matrix itself.

We connect a laptop via an external monitor

If an image appears on an external monitor or TV when a laptop is connected to it, then the problem is either with the cable or with the matrix (screen).

If all else fails

If, after completing all the above steps, your laptop still does not start and is still in a black screen state when turned on, this means that there are problems with the motherboard that can hardly be solved at home without special equipment and skills.

Bridges and graphics card of laptop motherboard

  • BIOS corruption;
  • Failure of the video card / processor;
  • Failure of the north / south bridge.

In the case of the last two options, the repair will cost about 100, depending on the installed processor or video card.

Screen check

If the screen remains black when you press the power button, but you can hear that the cooling system has started working and other signs of turning on the laptop are visible, then we try to connect an external monitor to it.

If a picture appears on the external monitor when the laptop is turned on, then the problem clearly lies in the laptop screen. Perhaps he has a damaged matrix or cable, but you can hardly diagnose this yourself. But before asking for qualified help, try two more ways to fix the problem described below.

Reasons why the screen remains black when you turn on the laptop

There are several reasons why you see a black screen instead of the desktop:

  • Video card problem.
  • Damage to the motherboard due to overheating of the device.
  • Faulty loop or screen matrix.
  • Battery failure.
  • RAM failure.
  • Incorrect hardware settings.

The last three problems can be dealt with at home; it is difficult to diagnose a physical malfunction of laptop components on your own, so you will have to contact a service center.

Reset BIOS

If you updated the BIOS or changed its settings before the problem appeared, then you need to roll back all the changes. For this, it is better to use an external monitor if it has an image on it:

  • Turn on the laptop by connecting an external monitor to it.
  • Go to BIOS (Delete or F2 key at startup).
  • Press F9 or on the “Exit” tab select “Load Setup Defaults”.
  • Confirm the decision by clicking “Ok”.
  • Press F10 and then “y” to exit BIOS with saving configuration.
  • In principle, these actions can be performed blindly, because all commands in the BIOS are entered from the keyboard, without the participation of the mouse. After BIOS reset, disconnect the external monitor and check if the screen works.

    When you turn on the laptop, the screen is black. Reasons and what to do

    In this article, we will give an answer to the question why, when you turn on (boot, start) a laptop, a black screen and what you should do in a similar situation. If it still beeps, then you will find the answer in the article Why the laptop beeps when turned on.

    The laptop does not boot because a black screen, or it starts up, makes a noise, but the screen does not turn on. the situation is not the most pleasant, moreover, it requires an immediate solution to the problem. This problem is widespread and often requires professional intervention. one of the laptop components is damaged and needs to be repaired using special equipment.

    Fixing the problem yourself

    Attention! We are not responsible for your actions. This article is for informational purposes only and does not call for action.

    The first step is to make sure the laptop is charged and the battery is working properly. We connect the laptop to the network (if it was running on battery power), wait a bit, and then try to turn it on again. If this time the screen lights up, then the problem most likely lies in the battery. Disconnect the laptop from the mains and try to turn it on from the battery again to make sure that the problem is correctly identified.

    If the laptop does not work either from the mains or from the battery, try resetting the hardware settings:

    • Disconnecting the laptop from the outlet.
    • We take out the battery from the device. In most modern laptops, removing the battery requires disassembling the case, which requires special tools and knowledge. Better with a similar, contact the professionals.
    • Press the power key and hold it for about 20 seconds to remove the residual charge and reset the hardware settings.
    • Reinstall the battery and try to turn on the laptop.

    If these steps did not help to solve the problem and the screen continues to remain black, then you need to check the physical health of the display.

    Reinstalling the RAM module

    Another reason for the black screen is a faulty RAM module. This is especially true for a situation when liquid got on the laptop, after which it stopped turning on.

    Important: the described actions are not recommended to be performed on your own if you do not have the appropriate experience.

    • Unplug the laptop and remove the battery.
    • Remove the screws that secure the RAM cover. If there is no compartment, then you will have to remove the back panel of the laptop.
    • Locate the RAM board and carefully remove it by bending the latches to the sides.
  • Blow out the connectors, clean the module from dust.
  • Replace the board by sliding it into place at a 45 degree angle. Don’t forget about the clips.
  • Close the lid and try to turn on the laptop.
  • If none of the described methods helped to deal with the black screen when turning on the laptop, then the best solution would be to contact specialists who can correctly diagnose the cause of the problem and quickly fix it.

    A logo is shown on the screen, some inscriptions, and then everything disappears (Windows did not start loading)

    If something is shown on the screen, and then disappears or you see some inscriptions (error). most likely the problem lies in the fact that the laptop (computer) cannot find the boot data (for example, the Windows boot loader was damaged on the disk, or the disk was disconnected altogether due to the detached cable).

    Below I will analyze the main reasons for this behavior, and what is better to do.

    1) Check if you have inserted a CD / DVD disc, if you have forgotten a USB flash drive, etc.

    By default, the computer’s BIOS first tries to find boot records on flash drives, floppy disks, CDs, and only then on the hard drive.

    So if you forget to take out, say, a music CD. then the computer after shutdown (reboot) will start looking for boot records on it (it will not find them, because a disc with music) and will give you a “black” screen with an error of 1-2 sentences (for example, “Press any key to boot from CD. “).

    To avoid such a seemingly simple thing, be sure to check and remove all disks, floppy disks, flash drives from the PC.

    2) Look carefully at the error (inscriptions), if any. They often contain the cause of the problem.

    If you see some kind of error on the screen, even a small inscription in the corner of the screen. be sure to photograph (write down) it. Often times this simple message contains the solution.

    Error “reboot and select proper boot device or insert boot media in selected boot device and press a key” // PROVIDED AS AN EXAMPLE

    3) Is the Windows bootloader damaged? Attempt to restore

    The Windows bootloader can be damaged as a result of a virus infection of the PC, due to incorrect operation of the antivirus, inaccurate user actions, when updating the OS, etc. Even in the event of an abnormal shutdown of Windows (for example, during a power outage). it may become that after switching on you will encounter a similar problem.

    Most often, if the bootloader is damaged, an error should appear on the screen, like: “No bootable device found.”, “An operating system wasn’t found”, “reboot and select proper.”, Etc. But it also happens that there is simply nothing shown at all.

    Whatever it was, I recommend trying to restore the bootloader (for this you need an installation flash drive with Windows).

    4) Go to BIOS / UEFI and check if the hard disk, RAM, etc. devices are detected. Also try resetting BIOS settings to optimal

    If there is a failure in the BIOS settings. the computer may stop loading. It is also possible that the hard drive has ceased to be detected (for example, due to its breakdown or a loose cable). To find out if the computer sees the disk itself, determines its model. you need to go into the BIOS and see for yourself.

    Notebook BIOS settings (main page) / As an example

    5) If you have 2 video cards (integrated and discrete).

    If your computer (laptop) has two video cards (integrated and discrete). then try disabling one of them (most often this can be done with a discrete video card. By the way, with which there are most problems with overheating).

    You can disable one of the video cards in the BIOS settings (note that this can not be done in all versions). You need to find the Configuration section: it should have a parameter called something like “Graphic Device Settings”.

    It is recommended to turn off the discrete video card when you want to save battery power (important for laptops), when it malfunctions, when there is a lot of noise from the cooling system.

    6) RAM problem. Planks need to be tested.

    In general, in case of problems with memory bars, you can often see not a “black”, but a “blue” screen, the computer often reboots, various errors pop up, etc. Nevertheless, I recommend checking the RAM “up to the heap” too.

    In addition to the dough, it is recommended to remove the strips from the slots, clean their contacts with an ordinary eraser, brush off dust and the remnants of the eraser with a brush. This should be done carefully, on a clean, flat and dry surface. Do not forget to blow out the dust from the slots on the mat. board.

    If you have several memory sticks. then connect only one of them during troubleshooting. Try to start the computer with only this one plate (then turn off the PC, and connect another plate, and start the PC with it).

    Black screen when you turn on your computer, laptop

    Unfortunately, no one is immune from mistakes and problems. Even very careful users who monitor the security of their Windows sometimes encounter the absence of the usual image on the screen (in the common people they simply say: “I have a black screen.”).

    I don’t want to be trivial, but this problem has its own nuances. The thing is that each user understands completely different things under a black screen. One. this is when his windows booted, and instead of the wallpaper on the desktop. he sees just a fill in black, while the other’s. when there is nothing at all on the screen (not a single inscription).

    In order to somehow group the various causes and solutions, I have identified the three most typical behavior of the computer (laptop) and Windows OS (see right). In this article I will try to give an exhaustive answer and solution for each possible option. I think that many users, using the article, will be able to solve the problem on their own and save some money.

    Nothing is shown on the screen (even logos)

    By this option, I mean the complete absence of any image on the screen: i.e. there are no inscriptions, errors, neither immediately upon switching on, nor after. no logos appear (for example, Acer, Lenovo, etc. manufacturers).

    1) Check if the computer and monitor turn on at all, how the LEDs behave?

    The first thing to pay attention to is whether the LEDs on the case of the system unit and monitor are on. It is not uncommon when the power cord is accidentally pulled out of the outlet. Also, do not forget that there is another power switch on the system unit (it could be accidentally turned off, for example, when cleaning dust or when moving the unit).

    For laptop users: check if the battery is dead. Try to connect the charger and after a while turn on the device.

    READ  How to Enter BIOS on MSI Laptop

    I also recommend that you disconnect everything you can from your computer. leave the very minimum: monitor, keyboard (TV, speakers, printer, etc. for the duration of testing and troubleshooting. disconnect!).

    I don’t want to generalize, but such banal reasons account for about half of the problems with the absence of an image on the screen.

    2) Check if the cable from the video card to the monitor is firmly inserted, whether it is broken?

    It also often happens that the picture is missing on the screen due to the fact that the plug is not firmly inserted or the cable that connects the monitor to the system unit is completely interrupted. Disconnect the cable from the monitor and the system unit, carefully review it and reconnect it. If there is another similar cable. it is recommended to try it.

    Broken USB cable // Broken while transporting the device

    Also, when the monitor is not receiving a signal (for example, in case of problems with the cable), it often displays the error “No signal” (No Signal, Check Signal Cable, etc. derivatives).

    Cable not connected (Check Signal Cable)

    3) Try to shine a flashlight on the screen (the backlight may be out of order)

    The backlight sometimes fails on screens. If it is true. then you will not see anything on its surface: the image will become too dim. Try to shine an ordinary flashlight (table lamp) perpendicular to the screen. If the problem is with the screen. should see the part of the image where the flashlight beams fall.

    Backlight burned out. the image is visible only when the table lamp shines on the surface of the monitor

    4) The problem may be related to the second (external) monitor

    Some laptops have specials. keys to turn off the screen. They are needed to display images on an external monitor. If you connected an external monitor before, then it is quite possible that the laptop “remembered” this and transmits the image to an unconnected monitor (while its own is turned off).

    ASUS laptop. screen off (function key)

    5) The video card or monitor is out of order

    If you can hear the fan running, you see the LEDs blinking after turning on the computer, but there is no image on the screen. it may very well be that your video card has burned out (or the monitor itself has become unusable).

    Pay attention to the sounds: according to the POST standard (i.e. BIOS self-testing system), if the video card is burnt out and does not respond to requests for mat. board, one long and two short beeps should sound (note: a speaker (speaker) is installed in the system unit, which will “hum”).

    In general, I highly recommend connecting another monitor to your PC as a test and see if there is a picture on it. If the picture is. then the problem lies in your monitor, if not. probably a problem with the video card (or motherboard).

    Windows starts loading and then the screen goes black

    Approximate sequence of switching on the PC

    In this case, the overwhelming number of reasons are related to the Windows OS: for example, the system files of the OS could be damaged, the Explorer may not start, viruses and adware, etc.

    1) Problem with OS activation (Windows is not genuine)

    If your Windows OS activation fails (or you didn’t activate it at all). then on the desktop, instead of wallpaper and a beautiful picture, you will see a message on a black background stating that your copy of Windows is not genuine. Example below.

    Your copy of Windows is not genuine

    To be honest, I personally would not attribute this reason to the problem of the “black” screen. after all, you have the OS loaded, you can use it. In this case, I recommend either entering your key, or installing a legal copy of Windows 10 (you can download it officially and free of charge from Microsoft itself).

    2) Windows bootloader may be damaged

    3) Try to boot in safe mode (there may be a driver conflict, for example)

    Often, when updating or installing drivers (and some other software), it may happen that after rebooting the PC. Windows will “refuse” to boot. This can happen due to a driver conflict (for example).

    In any case, I recommend trying to boot Windows in Safe Mode (this mode loads only the most important processes necessary for the OS to work. Thus, it starts even in the most hopeless cases.).

    Most often, to enter safe mode, immediately after turning on the PC. you need to press the F8 key several times. Next, a window should appear with the choice of the boot mode. An example is shown below.

    When you boot into Safe Mode, remove the last installed applications and drivers, after which your OS stopped loading. It will also not be superfluous to conduct an anti-virus scan of the system.

    4) Perhaps the problem is related to the explorer (it may simply not start)

    Try to hold down the CtrlAltDel keys at the same time and open the task manager. If the task manager starts. already not bad (it means Windows was booted, the explorer just did not start).

    To start Explorer, in the task manager, click “File / start new task”. Then type explorer in the “open” line and press Enter. After starting the explorer, you should see the familiar desktop.

    5) Possible infection with adware and viruses

    Problems with loading the OS can be associated with the action of viruses. For example, some viruses block the desktop, show various banners, preventing the user from reaching their shortcuts (to at least learn how to deal with this).

    It is recommended to check the entire system drive with a modern antivirus. How to do this if Windows does not boot normally:

    • use safe mode (how to enter it, I described above). In safe mode, you can also open some pre-loaded antivirus. the same Dr.Web Cureit and completely drive the system.
    • boot from a LiveCD disk (or flash drive). This “thing” does not require installation on a hard drive and works autonomously: and having booted from it, you can easily drive all hard drives connected to the system.

    6) System recovery and reinstallation

    Well, the last thing I recommend. this is to try to restore the system (if, of course, you have checkpoints).

    If the restoration does not help, only the last and correct solution remains. reinstall the system (although I am not a supporter of this, but with some problems, it is easier to rearrange the system than to “get to the bottom” of the truth).

    Nothing is shown on the screen (even logos)

    By this option, I mean the complete absence of any image on the screen (after turning on the device): i.e. there are no inscriptions, errors, neither immediately upon turning on, nor after. no logos even appear (for example, Acer, Lenovo, etc. manufacturers).

    1) Check if the computer and monitor turn on at all, how the LEDs behave?

    The first thing to pay attention to is whether the LEDs on the case of the system unit and monitor are on. Often when the power cord is accidentally pulled out of the outlet.

    Also, do not forget that there is another power switch on the system unit (it could be accidentally turned off, for example, when cleaning dust or when moving the unit).

    For laptop users: check if the battery is dead. Try to connect the charger and after a while turn on the device.

    I also recommend that you disconnect everything you can from your computer. leave the very minimum: monitor, keyboard (TV, speakers, printer, etc. for the duration of testing and troubleshooting. disconnect!).

    I don’t want to generalize, but such banal reasons account for about half of the problems with the absence of an image on the screen.

    2) Check if the cable from the video card to the monitor is firmly inserted, whether it is broken?

    It also often happens that the picture is missing on the screen due to the fact that the plug is not firmly inserted or the cable that connects the monitor to the system unit is completely interrupted.

    Disconnect the cable from the monitor and the system unit, carefully review it and reconnect it. If there is another similar cable, it is recommended to try it.

    Also, when the monitor is not receiving a signal (for example, in case of problems with the cable), it often displays the error “No signal” (No Signal, Check Signal Cable, etc. derivatives).

    3) Try to shine a flashlight on the screen (the backlight may be out of order)

    The backlight sometimes fails on screens. If it is true. then you will not see anything on its surface: the image will become too dim.

    Backlight burned out. the image is visible only when the table lamp shines on the surface of the monitor

    4) The problem may be related to the second (external) monitor

    Some laptops have specials. keys to turn off the screen. They are needed to display the image on an external monitor.

    If you connected an external monitor before, then it is quite possible that the laptop “remembered” this and transmits the image to an unconnected monitor (while its own is turned off).

    5) The video card or monitor is out of order

    If you hear how the fan is working, you see blinking LEDs after turning on the computer, but there is no image on the screen. it may very well be that your video card has burned out (or the monitor itself has become unusable).

    Pay attention to the sounds: according to the POST standard (i.e. BIOS self-test system). if the video card is burned out and does not respond to requests for mat. board, one long and two short beeps should sound (note: a speaker (speaker) is installed in the system unit, which will “hum”).

    In general, I highly recommend connecting another monitor to your PC as a test and see if there is a picture on it. If there is a picture, then the problem lies in your monitor, if not, there is probably a problem with the video card (or motherboard).

    Black screen when you turn on your computer, laptop. What to do?

    Good day!

    Unfortunately, no one is immune from mistakes and problems. Even very careful users who monitor the security of their Windows sometimes encounter the absence of the usual image on the screen (in common people they simply say: “I have a black screen.”).

    I don’t want to be trivial, but this problem has its own nuances. The thing is that each user understands completely different things under a black screen.

    For one, this is when his Windows has booted, and instead of the wallpaper on the desktop, he simply sees a fill in black, and for the other, when there is nothing on the screen at all (not a single inscription).

    In order to somehow group the various causes and solutions, I have identified the three most typical behavior of a computer (laptop) and Windows OS (see ).

    In this article I will try to give an exhaustive answer and solution for each possible option. I think that many users, using the article, will be able to solve the problem on their own and save some money.

    A logo is shown on the screen, some inscriptions, and then everything disappears (Windows did not start loading)

    If something is shown on the screen and then disappears or you see some inscriptions (error). most likely the problem lies in the fact that the laptop (computer) cannot find the boot data (for example, the Windows bootloader was damaged on the disk, or the disk is completely disconnected due to the detached cable).

    Below I will analyze the main reasons for this behavior, and what is better to do.

    1) Check if you have inserted a CD / DVD disc, if you have forgotten a USB flash drive, etc.

    By default, the computer’s BIOS first tries to find boot records on flash drives, floppy disks, CDs, and only then on the hard drive.

    Therefore, if you forget to take out, say, a music CD, the computer, after shutting down (rebooting), will start looking for boot records on it (it will not find them, because a disc with music) and will give you a “black” screen with an error in 1-2 sentences (for example, “Press any key to boot from CD.”).

    To avoid such a seemingly simple thing, be sure to check and remove all disks, floppy disks, flash drives from the PC.

    2) Look carefully at the error (inscriptions), if any. They often contain the cause of the problem.

    If you see an error on your screen, even a small inscription in the corner of the screen, be sure to take a photo (write down) it. Often times this simple message contains the solution.

    Error “reboot and select proper boot device or insert boot media in selected boot device and press a key” // PROVIDED AS AN EXAMPLE

    For example, the error “reboot and select proper boot.” (Given as an example) is treated here according to this instruction.

    3) Is the Windows bootloader damaged? Attempt to restore

    The Windows loader can be damaged as a result of a virus infection of the PC, when updating the OS, inaccurate user actions, due to incorrect operation of the antivirus, etc.

    Even in the event of an emergency shutdown of Windows (for example, during a power outage). it may so become that after turning on you will encounter a similar problem.

    Most often, if the bootloader is damaged, an error should appear on the screen, like: “No bootable device found.”, “An operating system wasn’t found”, “reboot and select proper.”, Etc. But it also happens that there is simply nothing shown at all.

    Whatever it was, I recommend trying to restore the bootloader (for this you need an installation flash drive with Windows). About how to do everything in steps, this article will tell you.

    4) Go to BIOS / UEFI and check if the hard disk, RAM, etc. devices are detected. Also try resetting BIOS settings to optimal

    If the BIOS settings fail, the computer may stop booting. It is also possible that the hard drive has ceased to be detected (for example, due to its breakdown or a loose cable).

    To find out whether the computer sees the disk itself, whether it determines its model, you need to go into the BIOS and see for yourself.

    How to reset BIOS settings // reset BIOS password on laptop and PC.

    Notebook BIOS settings (main page) / As an example

    5) If you have 2 video cards (integrated and discrete)

    If your computer (laptop) has two video cards (integrated and discrete), then try disabling one of them (most often this can be done with a discrete video card. By the way, with which there are most problems with overheating).

    You can disable one of the video cards in the BIOS settings (note that this can not be done in all versions). You need to find the Configuration section: it should have a parameter called something like “Graphic Device Settings”.

    It is recommended to turn off the discrete video card when you want to save battery power (important for laptops), when it malfunctions, when there is a lot of noise from the cooling system.

    6) RAM problem. Planks need to be tested

    In general, in case of problems with memory bars, you can often see not a “black”, but a “blue” screen, the computer often reboots, various errors pop up, etc. Nevertheless, I recommend checking the RAM “up to the heap” too.

    How to test RAM. see step by step example

    In addition to the dough, it is recommended to remove the strips from the slots, clean their contacts with an ordinary eraser, brush off dust and the remnants of the eraser with a brush. This should be done carefully, on a clean, flat and dry surface. Do not forget to blow out the dust from the slots on the mat. board.

    If you have several dies of RAM, then connect only one of them for the time of troubleshooting. Try to start the computer with only this one plate (then turn off the PC, and connect another plate, and start the PC with it).

    Windows starts loading and then the screen goes black

    Approximate sequence of switching on the PC

    In this case, the overwhelming number of reasons are related to the Windows OS: for example, the system files of the OS could be damaged, the Explorer may not start, viruses and adware, etc.

    1) Problem with OS activation (Windows is not genuine)

    If your Windows OS activation fails (or you did not activate it at all), then on the desktop, instead of the wallpaper and a beautiful picture, you will see a message on a black background stating that your copy of Windows is not genuine. See example below.

    Your copy of Windows is not genuine

    To be honest, I personally would not attribute this reason to the problem of the “black” screen. after all, you have the OS loaded, you can use it. In this case, I recommend either entering your key, or installing a legal copy of Windows 10 (you can download it officially and free of charge from Microsoft itself).

    2) Windows bootloader may be damaged

    I already wrote about the bootloader just above in the article. Here I will also give a link to instructions on how to restore it (for Windows 10).

    3) Try to boot in safe mode (there may be a driver conflict, for example)

    Often, when updating or installing drivers (and some other software), it may happen that after restarting the PC. Windows will “refuse” to boot. This can happen due to a driver conflict (for example).

    In any case, I recommend trying to boot Windows in Safe Mode (this mode loads only the most important processes necessary for the OS to work. Thus, it starts even in the most hopeless cases.).

    Most often, to enter safe mode, immediately after turning on the PC. you need to press the F8 key several times. Next, a window should appear with the choice of the boot mode. An example is shown below.

    When you boot into Safe Mode, remove the last installed applications and drivers, after which your OS stopped loading. It will also not be superfluous to conduct an anti-virus scan of the system.

    How to remove viruses from your computer if the antivirus does not see them. see step-by-step instructions

    4) Perhaps the problem is related to the explorer (it may simply not start)

    Try to hold down the CtrlAltDel keys at the same time and open the task manager. If the task manager starts. already not bad (it means Windows was booted, the explorer just did not start).

    To start Explorer, in the task manager, click “File / start new task”. Then type explorer in the “open” line and press Enter. After starting the explorer, you should see the familiar desktop.

    5) Possible infection with adware and viruses

    Problems with loading the OS can be associated with the action of viruses. For example, some viruses block the desktop, show various banners, preventing the user from reaching their shortcuts (to at least learn how to deal with this).

    It is recommended to check the entire system drive with a modern antivirus. How to do this if Windows does not boot normally:

    • use safe mode. In safe mode, you can also open some pre-loaded antivirus. the same Dr.Web Cureit and run it completely through the system. I recommend for this case; online antivirus software that does not need to be installed;
    • boot from LiveCD-disk (or flash drive). This “thing” does not require installation on a hard drive and works autonomously: and having booted from it, you can easily drive all hard drives connected to the system. About how to burn such a disc and check the PC with it, see the article.

    6) System recovery and reinstallation

    Well, the last thing I recommend is to try to restore the system (if, of course, you have checkpoints).

    If the recovery does not help, there is only the last and correct solution. to reinstall the system (although I am not a supporter of this, but with some problems, it is easier to rearrange the system than to “get to the bottom” of the truth).

    Possible reasons

    Before we begin to figure out why after turning on, instead of the usual Windows boot, you see a black screen and a cursor, let’s see the possible causes of this problem:

    • Installing an unlicensed copy of the system.
    • Damage to system files or registry.
    • Viral infection.
    • Video card driver problems.
    • Hardware faults.

    If the black screen does not appear immediately, but when Windows starts, try loading the last known good configuration. Windows 7 users need:

    • Restart your computer (laptop).
    • At startup, press F8 until the menu appears.
    • Select Last Known Good Configuration Boot.

    Unfortunately, this convenient option is not available on Windows 8. Therefore, you will have to check the system through safe mode (if the last good configuration on Windows 7 did not help, also use safe mode).

    Error message

    If a black screen appears with inscriptions, then you need to rewrite or remember the information that the computer is trying to transmit. Typically, the specific cause of the problem is listed. for example, “Bootmgr is missing”. The computer told you what the problem is, you just have to see what to do in a specific situation.

    A black (blue) screen with white letters also appears when you run Check Disk. If the system was terminated abnormally, then when the computer is turned on, an error check will be launched.

    Do not interrupt the operation. wait for it to finish, then the next time the system is started, it will no longer turn on. If you cancel the check, then a screen with white letters will appear every time the computer starts.

    Safe Mode Operation

    Start Safe Mode with loading network drivers using the F8 key or the installation media with Windows 8. If the system starts up correctly, then you need to check that there is no inscription in the corner that you are using a copy that is not genuine.

    If there is an inscription, then you can remove the black screen by using the correct Windows activation or buying a license key. Alternatively, try performing a system restore by rolling back to a date when the black screen did not interfere with your work.

    It is definitely worth checking the video card drivers:

    • Open the device manager.
    • Find your video adapter.
    • Open properties and go to “Driver”.
    • Select “Rollback”.

    If rolling back the drivers does not help, try the opposite action. update the software of the video card.

    • Click WinR and run “dxdiag”.
    • On the “Display” tab, look at the device name and driver version.
    • Search the Internet for the software for your video card model and update the drivers.

    Another point is to check your computer for viruses. Use antivirus and cleaning utilities (Dr. Web CureIt, Kaspersky Virus Removal Tool) to increase scanning efficiency. Remove all malicious applications before trying to boot the system again normally.

    Black screen on a laptop or computer: looking for the cause and troubleshooting

    If, when you turn on the computer, a black screen fills the entire display space, then the first step is to check all the contacts. Make sure the monitor is plugged in and the indicator is on. Check the cable between the video card and monitor. If a black screen appears when you turn on the laptop, go directly to the next diagnostic step. checking the software and hardware status of the device.

    Hardware faults

    Hardware faults are more difficult to deal with. It’s good if there is no signal on the screen. most likely, the cable connecting the monitor and the video card just came off. If the screen appears without anything immediately after starting the computer, and there is no way to boot into safe mode, then you are faced with a hardware failure.

    • Inspect all ports and external cables. they must be intact.
    • Remove the cover of the system unit and carefully inspect the system components, as well as the cables. Pay special attention to the video card. there should be no damage or dirt on it.
    • Remove all the RAM modules one by one, wipe the contacts, then reinstall the brackets.
    • Clean the system unit (laptop) from dust.

    A squeak coming from the motherboard speaker will help determine the hardware malfunction. Find a fault map on the Internet that allows you to determine the nature of the error by the BIOS beeps.

    If the computer does not beep, then the motherboard itself may be damaged. This is probably the most annoying issue you can encounter. If you have already done everything possible, and there was no reaction from the computer, then you should contact the service center. home diagnostic methods have been exhausted.
