How to Fix It
1
If you can boot to desktop, open Command Prompt as Admin and run: sfc /scannow — if it reports unfixable errors, follow with: DISM /Online /Cleanup-Image /RestoreHealth then run sfc /scannow again
2
If you cannot boot normally, boot from a Windows installation USB, select 'Repair your computer' > Troubleshoot > Command Prompt, and run the same sfc and DISM commands
3
Run a full antivirus scan with Windows Defender or Malwarebytes to check for system file tampering
4
Check Event Viewer (eventvwr.msc) > Windows Logs > System for critical errors around the time of the crash to identify which process died
5
If started after a driver update, use Device Manager to roll back the driver or boot into Safe Mode and uninstall it
6
As a last resort, use the Windows Reset feature: Settings > System > Recovery > Reset this PC (choose 'Keep my files')
