How to fix a black screen on Windows startup
Meeting with a black screen on the monitor is always scary. Sometimes it is scarier than a blue screen of death, in which there are at least some signs of life. In this article, we will look at the common causes of this problem and how to fix a black screen on your computer.
Windows output to the wrong monitor
If you have configured your PC to use multiple monitors and the second screen is not connected, it may cause a black screen in Windows. How to solve this problem? Assuming you are on your operating system, double-click the Win P key followed by Enter. Is there no reaction? Then click Win P three times and then “Enter”. If this does not work, repeat the operation four times and click “Enter”.
The combination of these keys changes the display mode. Each press cycles through monitors and has the potential to re-appear your primary display.
The most obvious solution
Usually the reason for the appearance of the “Malevich square” is a poor connection of the cable from the monitor to the system unit. And if it is a laptop, then accidental pressing of the Fn and F2 keys may be the reason for the shutdown. Their simultaneous use causes the screen to turn on and off. Therefore, before we move on to other reasons, double check that all of the above things are in order.
Video output port changed
There are times when the default video port is changed without your permission. This usually happens after updating the Windows driver or graphics card driver. For example, when using a DVI cable, the port may change to HDMI. Or instead of the HDMI port of your video card, the default will be the one on the motherboard.
Try connecting the HDMI cable to different HDMI ports on your PC. Do it along with the above Win P tip.
Another option. restart PC in Safe Mode.
Choose one of the suggested download options and wait for the process to finish. If the image returned, most likely the problem lies in the video card drivers. Therefore, be sure to update them without delay. How to implement this, we will tell you in our article just below.
Disable onboard graphics
If you have one more in addition to the built-in video card, then you may also experience problems leading to a black screen when starting Windows. Disabling the integrated video card may fix the problem.
Restart your PC in Safe Mode.
Click Win R.
Type devmgmt.msc and click OK.
In the “Display adapters” section, you will see several video cards. Right click on the integrated graphics card (usually Intel or AMD) and click Disable. If you are not sure which of the video cards is built-in, you can disable them one by one and check if this solves the problem.
Blinking white line (cursor) when booting a computer or laptop. reasons and what to do
One of the most common user problems when booting a computer or laptop. both from the built-in HDD or SSD, and from a flash drive. is a black screen on which a white dash blinks, or rather, an underscore and no further loading occurs.
In this manual, in detail about what may be causing the problem and how to fix the situation if you encounter a white blinking dash when you boot your computer.
White dash on black screen when booting Windows 10
If the system is already installed on an HDD or SSD and during boot you saw a black screen with a blinking white cursor (or you see it sometimes when you turn it on, but next time it boots up normally), the reason may be problems with the bootloader, BIOS settings, and also some of the features of Windows 10, related to the Connected Standby mode (the first point is just about this).
Try the following solutions in this situation:
- If the problem appears when you turn on your computer or laptop for the first time, but disappears itself when you turn it off and then turn it on, then when Windows 10 boots normally again, disable the “Quick Start” function.
- Try turning off your computer or laptop by long holding the power button, then disconnect any USB drives and memory cards (and other devices, if recently connected), turn the computer back on.
- If the problem appeared immediately after installing Windows 10, in the BIOS (UEFI) of your computer, instead of booting from the HDD or SSD, select “Windows Boot Manager” as the first item (if there is such an item).
- If the problem appeared after disconnecting one of the disks, the reason may be that the system bootloader was on it (the system and the bootloader may be on different disks).
- If you reset the BIOS (or suspect that it reset itself), make sure the correct boot options are selected. For example, for a system installed on an MBR disk, Legacy (CSM, Compatibility Support Mode) boot must be enabled and Secure Boot disabled, and for GPT disks, disabling Legacy mode support can help.
- If none of the options work, there is only one disk on the computer and previously booting from it was successful, you can try to restore the Windows 10 bootloader, but before that, in the same command line (how to open it is described in the instructions for restoring the bootloader), execute checking disk for errors using chkdsk.
Blinking white cursor when booting from a USB flash drive
The second most frequent case is a blinking “white line” when booting a computer or laptop from a USB flash drive. Here, the reasons are usually the same: the boot mode in the BIOS does not correspond to the mode for which the flash drive was prepared, in some cases. the Secure Boot option is enabled when booting from a drive, for which it should be disabled.
Details about all these points in a separate article A computer or laptop does not see the bootable USB flash drive in the Boot Menu. the context of the instruction is different, but all the described actions are also suitable for solving the problem in question.

Laptop Screen went Black but still running Fix
I have such a problem, I’m doing everything right, but when I start from a flash drive, the wine 10 logo appears for a second and then this line what could be the problem?
And just from a hard disk (SSD) Windows boots properly, if without a USB flash drive?
With a flash drive, is it exactly the order with the most? It is possible to write another one (the flash drive itself and the other way can be used)?
When the dash is flashing, you need to press the button
I do not know if this is related, but it happens to me. For some unknown reason, a sound notification appears about disabling / enabling USB and very often literally every second, I tried to determine what kind of device it was, it did not work, then I restart the PC, but the system does not start, I see only a white cursor in the upper corner. Only after completely disconnecting from the network, it is possible to boot the system. What could it be? There is an error in the system or the equipment is out of order?
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.
Windows 10 won’t boot: black screen. what to do?
With the transition to a new operating system with a black screen when loading Windows 10, it is difficult to surprise anyone, that the most curious thing, so many different reasons can lead to this, that when you turn off your computer, you do not know what will happen when you turn it on. Let’s try together to deal with each situation and solve it.
Integrated adapter actions
You can use the method only in cases where you have an output for connecting the monitor to the motherboard. Try to connect the PC screen to this output, restart the computer and roll back all drivers for the discrete video card. This can only be done through the device manager.
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.
Disable Fast Startup
Having tested the “blind” method, we still won, but this is not for long, the problem may return, so we follow to the “Control Panel”, by pressing the RMB on “Start”, then:
- “Equipment and Sound”
- “Power supply”
- On the left, select “Actions of the power buttons”
- Above “Change options that are currently unavailable”
- Scroll down and in “Shutdown options” uncheck “Enable fast startup (recommended)”
- Save and try restart! After, everything should be stable.

Why does a black screen appear when launching games or Steam
Often a black screen occurs when launching demanding games. Computers with weak hardware often give this error. In fact, it is not difficult to cure a PC. Updating drivers or lowering the screen resolution may help. True, only if the system requirements are not much higher than the “filling” of the computer.
Problems with Windows Explorer
Explorer, or explorer. the most important component of the system. It is thanks to him that the user gets access to the file system, desktop and many other functions. Therefore, if it fails, it may cause a black screen when starting Windows 7. If this happens, try restarting. If it does not help, follow the steps in the Restore the System Registry section.
If the above methods did not help, reinstall the system with a complete cleanup of the system partition. Reinstallation solves all problems, except for physical damage to the video card or hard drive.
Checking and removing viruses
Malware also causes display failures. Perform a full scan of the PC with built-in or third-party antivirus, delete the found files and restart the PC. If a virus was the fault of the black screen, then it will no longer bother you.
Decrease the screen resolution
It’s not uncommon for the hardware to keep up with the resolution of the display. This may cause a black screen with the cursor to appear. Decrease the screen resolution in “Options”. “System”. “Display”. Artificially reducing the screen can help if your old PC doesn’t quite handle the graphics.
