Windows 7 shuts down & restarts periodically.


  • Every now and again, my windows 7 64 bit Professional will shut down & restart out of the blue for (what I can tell) no apparent reason.  This is a new computer and all I did was update it from Home to Pro & I didn't use if for long before updating so I can't say if it would have done this when it was Home or not.

    I tried looking thru the events logs to find an answer to what is causing this.  I see in the logs where it says that the computer was unexpectanty restarted but I can't find out why.  This is frustrating.  I can use the computer for hours without it happening but it eventually restarts on its own.  It is not updating & is not setup to automatically install & restart so I know it is not that.

    Can someone point me to where I should be looking to find an answer  A big thank you to all of you who monitor this board to help those of us who are clueless!!!

  • You may boot in Clean Boot Mode as BSOD can be caused by programs that are running in kernel mode.

    Perform a clean startup to determine whether background programs are interfering with your game or program

    If the issue persists in Clean Boot Mode you can try to check the driver signature. To do so, in Start Search box enter sigverif.exe. Then click the start button in “File Signature Verification”. In the result list, please pick up *.sys files, rename one of them and then shut down or restart to check if the issue still occurs. If the issue persists, rename another *.sys file listed in the result of driver signature verifying, and check result again. By doing so we can determine which un-singed driver is the root cause.

    Another way is enable muni-dump and use Windbg. Please refer:

    How to read the small memory dump files that Windows creates for debugging

    You may paste the result in your next post for analyzing.
