Main Reasons for Windows 10 Black Screen

Many situations can cause this problem. For example:

  • The issue can happen after a graphics driver update or during the installation of a Windows feature update that contains a compatibility problem.
  • A buggy system update can also cause the issue.
  • A hardware-related issue with the display, connection, or video adapter is also a main cause of the issue.
  • A peripheral connected to your computer causes the problem.

This problem has many manifestations. For instance, your computer screen is black before signing in to Windows 10. Or, you get a black desktop screen even you sign in to Windows 10 successfully.

my desktop screen is black

No matter you have accessed the desktop or not, it is possible to solve the issue. You can just try the methods we introduce in the next part to help you out.

What to Do When Seeing a Black Screen before Signing in to Windows 10?

What if my computer screen is black before signing in to Windows 10? This part will show you some methods that are proved to be effective.

Fix 1: Check the connection between the display and your computer

If your computer goes to black before you sign in to your account, the biggest possibility is that there is a connection issue between the display and your computer.

Here are the things you can do to fix the connection issues:

  1. You need to make sure that all physical connections are correct. You can disconnect the video signal cable and then reconnect it to make a confirmation. You can also move the mouse to see whether your computer is in sleeping mode. You also need to make sure that the monitor is powered on.
  2. If your computer has more than one video output, you can switch to a different port and then mouse your mouse or press any key to wake up the display. At times, a driver update may contain changes, sending the video signal to the wrong port.
  3. If your computer has a discrete and integrated graphics card, you can make the connection to the embedded video processor to check whether there is something wrong with the card. At the same time, you need to consider one situation: a system or BIOS update can disable the discrete video card. If so, you need to re-enable it in the motherboard settings.
  4. If you are using an external monitor, you can go to the onboard monitor settings to increase the brightness because it may be the cause of Windows 10 black screen. Also, you need to check whether the monitor is using the correct input.
  5. If you are using a laptop, you can use the function keys to increase the brightness of the display.
  6. A broken display or video card, or cable can also cause the issue. You can connect the monitor to another normally working computer or use a different video signal cable. This can help you find the cause and take corresponding measures.

Fix 2: Detect the display

  1. This issue will happen if your Windows 10 loses the connection with the display. To rule out this possibility, you can press Win+Ctrl+Shift+B to restart the video driver and refresh the link to your monitor to have a try.
  2. If you are using a Windows tablet like Surface Pro, you can quickly press the volume up and volume down buttons three times at the same time to wake up the screen. When you are doing these operations, you can hear a beep and activity voice on the screen. If so, it means that the system has the response to the command and it is trying to create a connection with the display.
  3. If the system works, you can also press Win+P to call out the PROJECT menu. Next, you need to press the P key and then press Enter to switch between different display modes. This can bring back the normal screen. Please remember that you need to press P and Enter four times to cycle through all display modes until finding the proper one.


Fix 3: Restart your computer

If the screen shows you nothing but only a blank interface, you can force shut down your computer and then reboot it.

  1. Press and hold the Power button for about 10 seconds and then your computer will shut down.
  2. Press the Power button again to restart it.

This can remove the temporary errors that may cause Windows 10 black screen.
