Windows 10 crash, screen off keyboard blinks

Hello Quint,



Welcome to Microsoft Community.



To resolve this issue let us try the following steps:



Try disconnecting all external drives, and then restart the computer. Check if you are able to log-back to the desktop without the screen going off or the keyboard blinking. If the issue still persists then follow these steps.



Do you experience rapidly screen flicker/blinking after logging into the main Windows 10 Start Screen or do you experience this issue at the login screen itself?



If the issue appears after logging into the Windows 10 start screen then you may follow these steps:



If we see the screen flickering after sign-in there are two possible causes – apps causing Explorer to crash, or display driver issues.



To start, press this key combination: CTRL+SHIFT+ESC



If this opens Task Manager and that window is NOT flickering:

The likely cause is Software Compatibility issue causing Explorer.exe to crash repeatedly.

• Use the File, Run option in Task Manager to open additional tools as-needed. Be sure to check the box to run tools as Administrator. These could include:
  
  appwiz.cpl: Opens Programs and Features
  
  compmgmt.msc: Opens Computer Management
  
  cmd.exe
• You can search for crash events in the Event Logs and find if any third party DLLs are the faulting module in the Explorer,.exe crashes Or uninstall software that is likely to include shell extensions.
  
• If removing software does not resolve the issue, use these commands to repair Windows:
  
  dism /online /cleanup-image /restorehealth
  
  sfc /scannow

We have reports that removing these apps help resolve the issue:

• Norton Antivirus
• Other AV solutions
• iCloud
• IDT Audio (faulting module IDTNC64.cpl)

If Task Manager is flickering, or it didn’t open, proceed with display driver troubleshooting:

The likely cause is a display driver or display hardware issue.

• Boot to Safe Mode with Networking.
• Use the same steps here as for Black Screen issues – if dual chipset, disable built-in graphics, if still flickers, try with only the other chipset enabled.
  
• If this does not work, or there is only a single chipset, uninstall the device and remove the driver software.
  
• Then boot into Windows and update the drivers to the latest from the manufacturer.
  

Try the above steps and let us know the result.



Thank you.
