Since sfc, image restore, DDU, PSU, RAM swaps, and anti-cheat removal were already tried, the supported next steps are the standard Windows stop-code and unexpected-restart checks:
- Remove any newly added hardware, if any was added before the crashes started again. Shut down the PC, remove the hardware, and test again.
- Start in Safe Mode and check whether the random restarts continue there. If the system is stable in Safe Mode, continue the remaining checks from that state.
- Open Device Manager by right-clicking Start and selecting Device Manager. Look for any device with an exclamation mark
!. For any flagged device, right-click it and select Update driver. If that does not help, try Disable device or Uninstall device. - Check free disk space. Windows needs sufficient free space for swap files and other functions. Keep roughly 10% to 15% of the drive free.
- Install the latest Windows 11 updates: Start > Settings > Windows Update > Check for updates.
- If the issue continues, use a recovery option such as a System Restore point or another option under Recovery options in Windows 11. This can roll the system back to a state before the crashes returned.
A few relevant points from the available guidance:
- Unexpected restarts can be caused by a hardware device, its driver, or software.
- When Windows does show a stop error, the stop code and sometimes the module name can help identify the cause.
- If the screen is going blank without a stop code, that aligns more with blank/black screen troubleshooting than a normal BSOD path.
If the crashes happen with no dump file and no visible stop code, Safe Mode plus Device Manager and Windows Update are the most directly supported next checks from the available guidance.
