Windows 10: PC Restarts suddenly to black then starts up again.

Hello,


My pc just suddenly goes black and restarts. Sometimes it goes black and the screen wont come on again however the pc is still on. When i try and shut it off by holding down the power button, it doesn't work so I have to go and shut it off from the back. I'm rather sure this inst an overheating problem because I've checked the temperature of my components and all of them are within a good range. This issue also happens and gradually gets more frequent. However after I took all of my components out and put them back in, it kept happening however it began to happen less frequently until it stopped for a month or two until today. Any help would be MUCH APPRECIATED. This is a very very irritating issue. on average it happens every 5-10 minutes at its worst.



I don't know much about how windows works however by following a few youtube tutorials I found some logs on event viewer. Please note that these are just one or two examples of restarts that are on event viewer. The reasons can be different.

My home screen appears black with no start menu

Hi Muhamad,

You might be experiencing this issue because of corrupted system files or device drivers. To help us identify the cause of this problem, we would like to know the following information:

• Are you able to reach the sign-in screen when starting your computer?
• Have you made any changes to your computer before experiencing this issue?
• What troubleshooting steps have you tried so far?

In the meantime, we suggest that you perform the troubleshooting steps in the following link:

Troubleshoot black screen problems.

If you can reach the sign-in screen, we recommend that you start your PC in safe mode from the sign-in screen.
Safe mode starts Windows in a basic state, using a limited set of files and drivers. It can help you troubleshoot problems on your PC. Here are the steps:

• When you get to the sign-in screen, hold the Shift key down while you select the Power
  icon > Restart.
• After your PC restarts to the Choose an option screen, select
  Troubleshoot > Advanced options > Startup Settings > Restart.
• After your PC restarts, you'll see a list of options. Select 5 or
  F5 for Safe Mode with Networking.

Keep us updated on the status of the issue, and we will be glad to assist you further.

 

Windows 10 infinite restart black screen


Black screen after sign-in and you can see a mouse cursor:


Unplug your external devices

When you are at the black screen, try unplugging any peripherals you have plugged in at the time, and wait for a moment. If your screen becomes visible again, plug the peripherals back in one at a time.

Use Safe Mode

If unplugging peripherals not resolve the issue, for each of the troubleshooting steps below, you will need to use Safe Mode to troubleshoot this issue. To enter Safe Mode:

1. Reboot the PC, and when you reach the sign-in screen, hold the Shift key down while you click the Power button and select Restart.
2. When the system reboots, you will enter the Windows Recovery Environment.Select Troubleshoot, and then Advanced options, then Startup Settings, and Restart. When it restarts, you should see a number of options. Press 5 or F5 for Safe Mode with networking.

Reinstall your graphics card driver:

1. Once you’ve entered Safe Mode, right-click the Start icon and select Device Manager.
2. Expand Display Adapter.
3. Right-click your display adapter and select Uninstall. Then reboot your PC.

Check the registry

You may also see a black screen after signing in if the user interface has been replaced with software that is incompatible with Windows 10. You can check this in the registry. Warning: This solution will modify the registry. Serious problems might occur if you modify the registry incorrectly. Prior to attempting these steps, you should backup the registry for restoration in case problems occur.

1. Once you’ve entered Safe Mode, right-click the Start icon and select Run.
2. Type regedit.exe into the Open text box and click OK.
3. Navigate to the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
4. Click to select the WinLogon key, and then, in the right pane, click Shell. The value of Shell in the Data column should be explorer.exe. If the value of Shell isn't explorer.exe, double-click Shell, and then, in the Value data text field, enter explorer.exe, and then click OK.
5. Close the Registry Editor and then restart your PC.
   
   

Check for a corrupted user account

There could be a problem with the user account. To test this, create a new administrator user account and check if the new account also boots to a black screen:

1. Once you’ve entered Safe Mode, right-click the Start icon and select Command Prompt (Admin).
2. In the Command Prompt window, type the following commands (changing “<password>” to something of your choice):
   
   net user test <password> /add
   net localgroup Administrators test /add
