Screen goes black

Hi Kris,

It is possible that your screen goes black may be due to a critical system error which can cause the system to shut down. To isolate your issue, we'd like to gather more information:

• Have you made any recent changes prior to this issue?
• Did you get any error messages when it turns black?
• Have you tried checking if the sleep mode is turned on/off?
• What troubleshooting steps have you done so far?

Meanwhile, we recommend that you perform the steps in this
article to troubleshoot blank/black screen errors. This will provide you instruction when you see a black screen before signing in to Windows 10 and when you see a black or blank screen after signing in to Windows 10.

Let us know if you need further assistance.

 

SCREEN GOES BLACK!?

Hi,

If you see the black screen only after sign-in
and you can see a mouse cursor:

While at the black screen, try using CTRL+SHIFT+ESC to start Task Manager.

If it becomes visible, try finding LockAppHost.exe on the Details tab and ending the task.

If this resolves the black screen, use corruption resolution steps (dism, then sfc),

• • Press Windows+X.
  • Click on Command Prompt (Admin).
  • Type the command DISM.exe /Online /Cleanup-image /Restorehealth
    and hit Enter.
    • Run Sfc /scannow

and run the all apps PowerShell command in

PowerShell -ExecutionPolicy Unrestricted

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register


"$($_.InstallLocation)\AppXManifest.xml"}


If this does not work, use File, Run new task in Task Manager to start an Administrator CMD window. Use this to create a new administrator user with the following commands (changing “<password>” to something of the customer’s
choosing):

net user test <password> /add

net localgroup Administrators test /add

This will give you a test user to try, which will confirm if the issue is user or system-specific.

If you see the black screen or have a flickering screen before sign-in:

Try connecting to different video outputs on the PC. Sometimes a change in driver can cause the video to be sent:

• • To a different Adapter: from integrated graphics to a discrete card or vice versa.
    
  • To a different output: from HDMI to DVI, DisplayPort to VGA, or any other combination.
    

Try to boot into Safe Mode with Networking or Enable low-resolution video.

• • Advanced boot options, Safe Mode with Networking, or Low Resolution Video
    
  • Check Device Manager and look for Display Adapters
    • If you see 2 items under Display Adapters, disable to integrated video card (e.g. Intel HD 4000 or AMD Radeon HD 4200) and restart. (try vice versa if it does not work)
      
    • If you see 1 item under Display Adapters, rollback the driver or uninstall the display adapter in Device Manager, and enable the option to delete driver software.
      

Check the PC or display adapter manufacturer’s site for an updated driver.

Hope the information provided was helpful and do let us know if you need any assistance in the future. We will be glad to help.
