After turning on the laptop black screen what to do


The most common factor in the appearance of this problem is the inattention or inexperience of users: the plug through which power is supplied to the device may be damaged (in places where the cable is bent, this may not be visually visible, in fact, the thin cores of the wire are simply frayed due to repeated bending).

Or disconnected. This situation is especially true for older devices from Asus.

When operating on battery power, it may be discharged or uncharged, or the battery may be damaged.

You need to check everything and make sure that there are no such problems or solve them: charge the battery, replace the damaged cable, plug its plug into the outlet, if it is really working.

When you turn on the laptop, a black screen with the inscriptions

If when you turn on a laptop or computer, the operating system does not load, and the screen displays in English, this means that not everything is so bad and it is very likely that the problem can be solved on your own at home.

Any symbols on a black screen when the computer is turned on is a sign that almost all components of the computer are working normally and in most cases a software error.

when the computer starts up, a black screen with inscriptions in English

By this very inscription, as in the case of the beeps when turning on, you can determine the source of the problem. Try to read what is written on the screen and compare with the most common errors that occur in such cases.

Here is a list of the most common messages when you turn on your computer:

  • Reboot and select proper boot device and press a key. Does not see the boot device;
  • Floppy disk fail 40. Floppy disk drive error;
  • CMOS Checksum Error (bad). Replace the battery;
  • Cpu fan error. Problems with the CPU cooler;
  • Disk boot failure insert system disk and press enter. Does not see the boot device;
  • Smart status bad (Smart hard disk error 301). Problems with the hard disk;
  • Boot device not found. Does not see the boot device;
  • Ntldr is missing;
  • Invalid Partition Table.

If you find an inscription similar to the one that is displayed on your computer or laptop when you turn it on in the list above, then click on it and you will find information about its purpose, as well as all kinds of options for correcting it.

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.

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.

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.

To do this, you need to connect the laptop via a supported interface to an image output device.

For most, this is an outdated VGA port, although many modern devices are not equipped with it.

In this case, the common must be DVI or modern HDMI. There is no difference for the user, only the plugs and wires are different.

If a picture appears on the TV / monitor, then the problem lies in your display. the backlight is faulty, the problem is with the loop.

In the latter case, you can replace it on your own, but it is not always easy to find the necessary component, and even fewer people will be able to carefully and correctly untwist the device, replace the old cable and put everything back together. Yes, in such a way as not to harm the laptop.

When connecting the PC to the TV, a picture appeared on the latter. take the device to the service center.

Experts will find the problem and offer a solution. Sometimes it can be expensive, such as replacing the screen matrix.

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).


There are a lot of factors that cause a dark picture on the screen or its absence.

  • mechanical, chemical or other damage (often due to overheating, falling of the device or inept user intervention) of laptop components. it simply will not turn on;
  • problems with the cable that connects the screen matrix of the device to the motherboard. the device is loaded, there is simply no image;
  • failure of the RAM strips. the indicators may light up, the fan (s). work, but the picture will not be.

Dust problem

The fan blades and radiator tubes with fins are covered with dust, which reduces the thermal conductivity of the metal and the efficiency of removing warm air from heated power elements.

We’ll have to remove the bottom cover of the device and get rid of dust using a can of compressed air, cotton swabs (just don’t leave any lint) or a pile cleaner with a hairdryer.

If you are going to blow, it is better to take the laptop outside or on the balcony.

It is also recommended that every two years (each service center and manufacturer will set the terms independently) to replace the terpopast, which is located on the contact pad between the central processor and the cooler.

It is better not to replace the heat-conducting paste at home, if you do not have such experience, it is fraught with consequences.


To make sure that the battery is working, you need to connect power to the device, after which the corresponding indicator will light up: there is power supply and charging of the removable battery.

If the battery charging light does not glow, remove it from its seat, in most cases pulling out a pair of latches.

Then we take an eraser and clean the contacts on the battery and on the laptop, if they have something like a plaque or change the copper color to another (gray, greenish. they simply oxidized).

We hold down the power supply button so that the residual charge accumulated on the power elements is consumed.

Now you can insert the battery and try to turn on the device. Without a working adapter, connector and power cable, all these manipulations cannot be done.

If the following steps did not help, the removable battery is likely to be out of order.

The problem with contacts and operability of the RAM slats is another common reason for the absence of a picture on the laptop display or the inability to start it.

Often drinks poured onto the keyboard lead to this, the consequences of which were not eliminated in time (drying).

To check the RAM modules, you must do the following.

  • Disconnect the power cable from the mains and from the device.
  • Removing the battery.
  • We hold down the power button for a few seconds in order to use up the remaining charge.
  • Unscrew the bolts that hold the cover that covers the RAM strips.
  • We remove the RAM modules, for which you need to move in opposite directions two latches for each strip.
  • We clean the contacts (very carefully) using the same school eraser.
  • We insert them back and fix them in the sockets with latches.
  • We tighten the screws, put the cover back on, and turn on the device.

Using integrated video

If you have an output for connecting a monitor not from a discrete video card, but on the motherboard, try turning off the computer, connecting the monitor to this output and turning on the computer again.

There is a good chance (if the integrated adapter is not disabled in UEFI) that after turning on, you will see an image on the screen and be able to roll back the discrete video card drivers (through the device manager), install new ones, or use system restore.

Black screen in Windows 10

If after updating or installing Windows 10, as well as after rebooting an already successfully installed system, you are greeted with a black screen with a mouse pointer (and possibly without it), in the article below I will tell you about possible ways to fix the problem without resorting to reinstalling the system.

The problem is usually related to incorrect operation of NVidia and AMD Radeon video card drivers, however, this is not the only reason. As part of this instruction, we will consider the case (the most common recently) when, judging by all the signs (sounds, computer operation), Windows 10 boots, but nothing is displayed on the screen (except, possibly, the mouse pointer), it is also possible an option when a black screen appears after sleep or hibernation (or after turning off and then turning on the computer). Additional options for this problem in the instructions Windows 10 does not start. First, a few quick solutions for common situations.

  • If at the last shutdown of Windows 10 you saw the message Wait, do not turn off your computer (updates are being installed), and when you turn on you see a black screen. just wait, sometimes updates are installed this way, this can take up to half an hour, especially on slow laptops (Another symptom the fact that this is precisely the case. the high load on the processor caused by the Windows Modules Installer Worker).
  • In some cases, the problem may be caused by a connected second monitor. In this case, try to disable it, and if it did not work, then go into the system blindly (described below, in the section about rebooting), then press the WindowsP (English) keys, once the down key and Enter.
  • If you see a login screen and a black screen appears after login, then try the next option. On the login screen, click on the on-off button at the bottom right, and then hold down Shift and click Restart. In the menu that opens, select Diagnostics. Advanced Options. System Restore.

If you encounter the described problem after removing a virus from your computer, and you see a mouse pointer on the screen, then the following guide will most likely help you: The desktop does not load. what to do. There is another option: if the problem appeared after changing the structure of partitions on the hard disk or after damage to the HDD, then a black screen immediately after the boot logo, without any sounds, may be a sign of the volume unavailability with the system. Read more: Inaccessible_boot_device error in Windows 10 (see the section about the changed partition structure, despite the fact that the error text is not shown for you, this may be your case).

Restart Windows 10

One of the working ways to fix the problem with a black screen after re-enabling Windows 10, which seems to be quite workable for owners of AMD (ATI) Radeon graphics cards, is to completely restart the computer and then disable Fast Startup of Windows 10.

In order to do this blindly (two methods will be described), after booting the computer with a black screen, press the Backspace key several times (left arrow to delete a character). this will remove the lock screen saver and remove any characters from the password input field if you they were accidentally introduced there.

After that, switch the keyboard layout (if required, by default in Windows 10 it is usually Russian, you can switch it almost guaranteed with the Windows Spacebar keys) and enter your account password. Press Enter and wait for the system to boot.

The next step is to restart your computer. To do this, press the Windows key (key with the logo) R on the keyboard, wait 5-10 seconds, enter (again, you may need to switch the keyboard layout if you have Russian by default): shutdown / r and press Enter. After a few seconds, press Enter again and wait about a minute, the computer will have to reboot. quite possibly, this time you will see an image on the screen.

The second way to restart Windows 10 with a black screen is after turning on the computer, press the Backspace key several times (or you can use a space or any character), then press the Tab key five times (this will take us to the on / off icon on the lock screen), press Enter, then. the “Up” key and again Enter. After that, the computer will restart.

If none of these options allow you to restart your computer, you can try (potentially dangerous) force shutting down your computer by holding down the power button for a long time. And then turn it back on.

If, as a result of the above, the image appeared on the screen, then it is precisely in the operation of the video card drivers after a quick start (which is used by default in Windows 10) and to avoid a repetition of the error.

Disable Windows 10 Fast Startup:

  • Right-click on the Start button, select Control Panel, and in it. Power Options.
  • On the left, select Power Button Actions.
  • At the top, click “Change settings that are currently unavailable”.
  • Scroll down and uncheck “Enable Fast Startup”.

Save your changes. The problem should not repeat itself in the future.

Removing and reinstalling video card drivers

If the previous method did not work, you should try to remove the video card drivers from Windows 10. You can do this in safe mode or in low-resolution mode, and I will now tell you how to get into it, seeing only a black screen (two ways for different situations).

First option. On the login screen (black), press Backspace several times, then Tab 5 times, press Enter, then up once and holding Shift, Enter again. Wait about a minute (the diagnostics, recovery, system rollback menu will load, which you probably won’t see either).

  • Down three times. Enter. down two times. Enter. left two times.
  • For computers with BIOS and MBR. down once, Enter. For computers with UEFI. two times down. Enter. If you do not know which option you have. press “down” once, and if you get into the UEFI settings (BIOS), then use the option with two clicks.
  • Press Enter again.

The computer will reboot and show you the special boot options. Using the number keys 3 (F3) or 5 (F5) to start Low Resolution Mode or Safe Mode with Networking. Once booted, you can either try to run System Restore in the Control Panel, or delete the existing video card drivers, and then restart Windows 10 in normal mode (the image should appear) and reinstall them. (see Installing NVidia Drivers for Windows 10. for AMD Radeon the steps will be almost the same)

If this method of booting the computer for some reason does not work, you can try the following option:

  • Log in to Windows 10 with a password (as described at the beginning of the instructions).
  • Press WinX keys.
  • Press up 8 times, and then. Enter (the command line will open on behalf of the administrator).

At the command prompt, type (must be in English): bcdedit / set safeboot network and press Enter. After that, enter shutdown / r press Enter, after 10-20 seconds (or after a sound notification). Enter again and wait until the computer restarts: it should boot into safe mode, where you can remove the current video card drivers or start the system restore (In order to return the normal boot later, use the bcdedit / deletevalue safeboot command in the command line as administrator)

Additionally: if you have a bootable USB flash drive with Windows 10 or a recovery disc, then you can use them: Restore Windows 10 (you can try using restore points, as a last resort. resetting the system).

If the problem persists and you can’t figure it out, write (with details about what, how and after what actions happened and is happening), though I don’t promise that I can give a solution.

Write plz a way to disable the periphery of mb someone will help as me. I spent 3 hours, tried everything except disconnecting the periphery. In the end, it turned out that the problem was in a broken USB radio transmitter for the mouse, which stopped working normally a week ago, which I forgot about. This device blocked the system from booting and as soon as I turned it off everything immediately started working.

Good day. ASUS laptop after Windows 10 has been updated. When you turn on the black screen, the buttons turn on, the fan works. the drive is working. I tried to enter the BIOS, it does not enter. reinstalling Windows fails. I checked the RAM. It works, I changed it to a new one, or any urge to work. Monitor connected, does not see. Can you tell me how to turn it on. Or just to the service center to carry.

And how did they turn it off from the black screen? If you turn off by holding the power button for a long time, then the next time you turn it on, the BIOS should start.

Turned off for a long time. Tried it does not start in BIOS.

Such a problem, about six months ago, the light went out (I should say I have a laptop, the battery is not working, it works from the outlet), I turn it on, the automatic recovery is being prepared, after a black screen, I tried a lot (there was a flash drive with Windows (it is definitely working, Windows is recorded right)), in the boot menu it showed, wrote start boot device, like so, after a black screen with a blinking underline in the left corner, after the HP logo, again after a black screen), I admit that I could do something wrong (it seemed the opposite ), got tired, didn’t touch it for more than a month, went into BIOS to see what he was doing (changed boot from USB flash drive to OS boot manager in Uefi

This is the maximum that I did (I don’t remember for sure), the logo is loaded. a black screen (and then the mouse cursor appears and I understand that it will work now, and after 10 seconds it turns on), I did not understand at all how it worked, okay, let’s move on he worked for a month, everything is fine (they turn off the light again), and everything is the same as described earlier, I try to start the second day, and do I really have to wait a long time again for it to work, somehow I can’t believe that it’s a matter of time, maybe there are ways of what I don’t know, or is it worth starting from scratch (BIOS settings, etc., I’m ready to listen), I’ll be glad and wait for your answer.)

That is, preparation for automatic recovery is underway now? And what happens after it finishes (perhaps you need to wait a little longer)? If something is written in the spirit of “the computer is not started correctly” and there is a button “advanced options”, then there you can try restore points and restore at startup.

After preparing automatic recovery. a black screen appears and that’s it, I’ve been waiting for more than a few hours, nothing happens, the keyboard is working, the caps is on.

In such a situation, you can make a bootable USB flash drive with a 10 somewhere on another computer, boot from it on this computer, there, on the second screen (after choosing the language), at the bottom left, click “System Restore” and try the recovery tools from there, to begin with. restore points.

I made a bootable USB flash drive, launched it through the boot menu, immediately after that it says “Start booting from USB device” at the top, hangs for 5 seconds, then “_” appears in the upper left corner and blinks for 15 seconds, then the Windows logo appears, it lasts for 15 seconds and black screen (waited in this state for more than an hour, nothing happened).

The boot mode is correctly set in the BIOS, the same in which the flash drive is written?
We tried to disable Secure Boot?

Secure Boot is grayed out (disabled), Legacy Support (Enabled). when enabled. Network Boot Protocol (Ipv4 (Legacy), while UEFI boot Manager (in the first line of the OS boot Manager) and Legacy boot order (in the first line of Notebook Hard Drive) with such settings launched the USB flash drive through the boot menu, the result is the same.

And how was the flash drive “prepared”? Try to write off. Microsoft tool

I did it through UltraISO (I checked it on 2 laptops with 10 Windows x64, worked on both devices, I’ll do it well through the Microsoft office tool (access to the laptop will be tonight or tomorrow evening. then I’ll write) thank you.

Hello, sorry for such a delay (it was only the day before yesterday that it became possible to make a download file from an off-site site), when setting up the BIOS described earlier in the boot menu, a USB flash drive with a note (UEFI) appeared, when you select it, the laptop logo immediately appears and the boot circle below (after 15 seconds the logo disappears), the boot circle remains on the black screen (from 23:00 until the morning I left the laptop, nothing changed, the boot circle continued to spin), now you need to configure the BIOS or? I look forward to your advice, thanks.

Hm strange. According to your description, it turns out that it seems to “want” to boot (that is, we can assume that everything is in order in the BIOS).
I don’t know what to offer you remotely. Sometimes this behavior happens with faulty hard drives, but I’m not at all sure what this is about.

I hope the reason is not a hard drive breakdown (since a few months ago there was the same problem and after waiting for more than a month it worked, although this is very strange, I will probably leave it for a month and then try to start it), since there are no more options left.

I took it to the service center. They made a diagnosis, they said the BIOS went off. The programmer was restored. Everything worked.

Problem with wires and / or connectors

Typical situation. problems with cables, connectors and power buttons.

Technical difficulites

What if the black screen when the computer was turned on could not be defeated by the means described in this article. Perhaps the reason lies in a malfunction of parts of your PC.

If you are not an expert in the field of computer equipment repair, we recommend that you contact the service for professional support.!

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

Black screen when loading Windows is a problem that sooner or later many users face, but not everyone knows how to fix it. What do you need to do? First you need to examine the possible causes. There are many of them and they are different. They can be both technical and software, and sometimes the problem lies in the usual carelessness.

Incorrect refresh rate or too high resolution

The second common problem with a black screen when starting Windows can be the incorrectly set refresh rate on the video card. The fact is that old CRT monitors operate at a high screen refresh rate, up to 100 Hz and higher. And modern LCDs can only support 50-60 Hz. This is due to the design feature of such monitors.

If you got a black screen exactly when switching from an old monitor to a new one, then you need to do the following.

  • Connect the computer again to the old monitor.
  • Set the refresh rate to 60 Hz and the minimum screen resolution. This can be done in the properties of the screen or a special utility of the video card driver.
  • Connect the desktop to a new monitor and adjust the frequency and screen resolution for the new display.

For the same reasons, you can get a black screen on a laptop connected to an external monitor. Try adjusting the frequency and resolution for the external display as shown in the picture above.

“External Monitor”

A laptop almost always has an output for connecting an external monitor. Therefore, if, when you turn on the laptop, you hear the sound of the coolers, but the screen is black, then it is likely that someone switched it to work with an external monitor. Locate the external monitor function keys on the keyboard and try turning on the internal display. This is how they look on an ASUS laptop:

The F7 key turns off / on the internal screen, and F8 controls the combination of output to the external / internal laptop monitor. They should be pressed together with the function key, usually denoted Fn.

This is how the choice of operating modes with an external monitor looks like in Windows 8 and 10.

Different modes are switched by sequential pressing of the Fn and F8 key combination for the ASUS laptop keyboard shown above. So you can accidentally turn off the laptop’s internal monitor and get a black screen when turned on.

Software malfunctions

Checking the Power Supply to the Monitor

  • If you have a desktop computer, the first step is to check the power supply to the display. Some users get so used to working on a laptop that when they switch to a desktop, they do not notice the obvious. The power button on the monitor is just off. It is no coincidence that the instructions of IBM specialists, developed for the first PCs, assumed that the power supply was checked by the very first item.
  • The second common reason for a sudden black screen when turned on is insufficient power cable contact. In practice, there were often cases when the cable plug was loosely held in the socket, and turned off when the display was moved or the active participation of household members, including furry ones. In the office, poor cable-to-monitor contact is often caused by cleaners touching the wires while cleaning.

Using a restore point to roll back the system on the computer and fix problems on the PC

It happens that the reason for the failure of the OS is impossible to identify, removing drivers and programs that cause conflicts does not help: anyway, when the computer boots up, a black screen appears.

What to do about the problem? Reinstall the operating system? If Windows still boots when you turn on your computer, then do not rush to “bury” it. We recommend that you first try to roll back Windows to a working state using a restore point (you can do this by booting in Safe Mode). For more information on how to roll back the system, read the link.

Windows startup black screen: what to do if your computer won’t turn on

I don’t want to be trivial, but the so-called “black screen problem” when loading the operating system after turning on the computer. one of the most common problems faced by owners of both desktop and laptop computers. The operating system that won’t boot or the hard drive model is not very important in diagnosing the problem. How to remove the black screen when loading Windows 7, Windows 10 on a computer and laptop, the reasons for the failure, we will tell further.

This guide will be supplemented, so do not hesitate to ask questions, as I can, I will clarify technical issues and solve your problems with a black screen.

Disable unnecessary programs and services from Windows autorun

There is a wonderful utility msconfig, with its help you can speed up Windows boot. Although modern computers load the OS quickly, boot optimization can remove the black screen for a few seconds.

  • Start. Execute. In the window, enter msconfig.
  • Services tab. here you can disable unnecessary services.
  • Startup tab. to enable / disable programs at boot.

In Windows 10, startup items can be disabled through the Task Manager (Startup tab). The status column displays the status of the application.

Frequently asked Questions

After entering the BIOS password, there is no Windows 7 boot icon, the monitor has turned off (went into power-saving mode), the f8 key does not work.

  • Try to reset the BIOS by removing the battery from the motherboard.
  • The power-saving mode will not work immediately after starting the computer; rather, the problem is related to one of the components. Check the connection of the video card from the motherboard, the video card to the monitor, etc.
  • If everything is in order with the BIOS, and Windows 7 does not boot, reinstall the OS. This seems to be the easiest method to get rid of the black screen.

After changing to Windows 7 from 32bit to 64bit, a black screen began to appear. Everything works when connected to a TV.

It is possible that the 64-bit version does not have drivers installed on the monitor or video card. Check the manufacturer’s website if the monitor supports this OS. There is a suspicion that your particular vga monitor is not supported by this edition of Windows. Try to boot Windows in safe mode or with the option “Enable low-resolution video mode (640×480)”.

I am using VirtualBox with Linux. Turned off the virtual machine, after boot. black screen with an underscore on the left.

If you save the state on the virtual machine (Suspend), in principle, no problems should arise. If you turn off the virtual machine, then Linux tries to boot when you turn it on. Why a black screen with an underscore appears after a Linux reboot is a separate question. Check the key settings of the virtual machine. If the error persists, try installing Linux on Vmware Player.

When I turned on the computer, nothing appeared. The camera is working and the computer is on. What is the problem. RAM or hard drive?

To diagnose the problem, it is advisable to recall previous events. Did the computer show any symptoms of a breakdown (hard disk noise), did you delete system files on the disk, etc. This will help narrow down the list of possible causes. Next. watch at what stage the black screen appears. If the hardware initialization is successful, then the problem is in the operating system. that is, Windows does not start. In this case, we advise you to reinstall the OS from a bootable USB flash drive or disk.

I changed the video card. I start the PC. there is a BIOS, and then just a dark screen. This is because of the drivers?

Maybe. Go to Windows Safe Mode, uninstall old drivers and install new ones. Then restart your PC. If it doesn’t help, read the entire article.

We remove programs that conflict and block the OS loading at startup

I can’t start Windows 7. When you turn on the computer, after the words “Windows start” a black screen appears and then the PC does not boot. There is no cursor. I restart my computer, I am given the choice of how to boot Windows, I choose normal mode. and everything turns on, sometimes you need to reboot several times. Normally, it does not turn on at all, I have Ccleaner, I use it, the antivirus is Avast, I do not update any drivers. What could be the problem?

In this case, the sequence of actions for elimination of the problem will be approximately the same as in the above case. The only thing is that in Windows Safe Boot Mode, you need to specify the “Enable Safe Mode” item. Further, in this download mode, you need to go to the control panel and in the “Programs and Features” window, sort by the date the applications were installed. Analyze what you have installed recently: it is possible that conflicting applications are the reason for the black screen and inadequate loading of Windows from the system disk on the PC. One of the best software for uninstalling applications. free utility CCleaner.

Viruses have damaged Windows system files

Many computer viruses are capable of deleting or damaging important system files. As a result, after loading Windows, a black screen appears, although the cursor may be displayed and react to your movements. Removing viruses does not always solve the problem, but you can try.

How to check your hard drive for viruses if Windows won’t boot? You need a work computer to which you can attach a hard drive. Once booted under Windows, install the free Dr Web CureIt antivirus. The CureIt utility contains up-to-date virus databases.

Select the hard drive to scan and run the scanner.

If, after detecting viruses, a black screen appears when Windows starts up anyway, then you need to look for other reasons.

We write down the USB flash drive for recovery and reinstall Windows

After updating Windows 7. a black screen in any mode: normal, safe. no difference. I tried to restore Windows through the installation disk. to no avail.

Answer. Install Windows 7 from scratch or immediately install Windows 10, thereby killing two birds with one stone: update and solve the problem with a black screen when loading Windows 7.

One of the most dramatic ways to get around a black screen on boot. reinstall a stable operating system. Once upon a time, many of us used an installation CD / DVD to solve such problems (see above). Already after the arrival of Window 7 on the desktop PC market, the need for a floppy drive was gradually decreasing, and today it is the most convenient way to install Windows. this is creating a bootable USB flash drive and restoring in boot mode from a USB drive. In general, read a practical guide on how to make a bootable Windows 8 USB flash drive.

One of the best programs for writing Windows to a USB flash drive. Rufus. The utility is available in Russian, it is free and, as a rule, writes fail-safe USB sticks for installing Windows.

Start Windows in Safe Mode on your computer

One of the most likely reasons why Windows or another operating system won’t boot. system conflict due to which the OS cannot work correctly after turning on the PC. This can be caused, for example, by the fact that the user installs an incompatible program or drivers that conflict with Windows, and when the laptop / PC is turned on, the conflict will manifest itself from an unpleasant side. in the form of a black screen. How to remove it?

Fortunately, the Windows developers have provided a safe mode to log on to the operating system, which is specifically designed to address various compatibility issues. By entering safe mode, you can remove all problems on the computer, resolve conflicts, and then boot Windows in normal mode.

So, to enter Safe Mode on a computer:

  • Remove from the computer all media and devices that may affect the boot of Windows (flash drives, disks, etc.)
  • Restart or turn on the computer, depending on its current state.
  • To enter Safe Mode, hold down the F8 key during boot. If there are several operating systems on the PC (laptop or desktop version), then select the appropriate one from the list and then hold down F8 again to go to Windows Safe Boot Mode.

Further, in the boot options in safe mode, you can select one of the items and solve the problems of a black screen on a laptop or desktop PC.
