Where do I find what caused the WER fault?

When I restart or manually power down my computer when I observe unusual activity (in the latest case, RBG lights turned off on both channels monitoring CPU temperature), I see a WER fault message on the screen momentarily before the screen blanks and the computer goes through its rebooting process. What is causing this to occur, and where can I go to see this information/log file?

    Check the reliability monitor.

    Hello

Thank you for your question and reaching out.


The WerFault.exe process is a crucial part of the Windows Error Reporting Service in computers running the Windows operating system. It is the duty of this component to disseminate information and alerts on application errors, crashes, and other potential issues in System Applications. Therefore, if WerFault.exe is damaged or deleted, it's possible that the "Werfault.exe Application Error" will manifest. The system would be unable to operate properly because of this issue.


1. Disable any Antivirus program or Windows firewall you may have for temporary purpose.

2. Cleanup below Temp folders location -> Open Start -> Run -> Type below location one-by-one and press enter 
    ->  C:\Windows\Temp
    ->   %USERPROFILE%\AppData\Local\Temp

3. Run Disk Cleanup from Select C:\ Drive from Properties- > General -> Disk Cleanup - >Cleanup system files

4. Run sfc /scannow from elevated prompt.

5.  Run below DISM commands  from elevated prompt.

DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online  /Cleanup-Image /RestoreHealth

6.  Disable fast startup using below command.

Powercfg -h off
