    Computer Blue Screens or Shut Offs when I lock it


    I always lock my office computer when I step away for a bit whether its 5 min or for lunch etc and notice that sometimes when I come back I am greeted with a restarted computer and a new dump file. This has been ongoing for a while, but I can't recreate it (by simply locking the computer and waiting a bit) so I am guessing its one particular task that is causing the issue. I have attached the dump file and welcome any assistance.

    There was no mini-dump file created. Can you provide a link to the memory.dmp file (post it to OneDrive or Dropbox)?

    Code:
    2018-04-11T11:37:46.815		The computer has rebooted from a bugcheck.  The bugcheck was: 0x0000003b (0x00000000c0000096, 0xfffff8000ed879cb, 0xffffb408ae1efa50, 0x0000000000000000). 
    A dump was saved in: C:\WINDOWS\MEMORY.DMP. Report Id: 00000000-0000-0000-0000-000000000000.

    The latest crash was different - this time it was 0x154 UNEXPECTED_STORE_EXCEPTION.

    I would be concerned that the hard disk might be giving problems. I wonder if it is being triggered by some sort of disk cleanup or optimisation task starting in the background?




    Diagnostics Test

     HDD TEST


    Run HDTune to
    • check the health,
    • scan for errors, no quick scan but full scan
    • run a benchmark.

    It may take some time, but please take the time you need to perform it properly.
    When above is done please make screenshots of the following
    • the health,
    • the error scan,
    • the benchmark incl. following
      • transfer rate,
      • access time,
      • burst rate,
      • cpu usage.


    Here is the processor thread at the time of the crash:

    Drives look OK. We might need to wait for a few more BSOD crashes and hope you can capture the mini-dumps.

    Got another yesterday although I wasn't at the computer when it happened and the computer was simply idling.

    You still have Driver Verifier turned ON. Please turn this off as it is not good to leave it running all the time.

    Turned off verifier but didnt restart right away. Got another BSOD before restarting after I locked the computer and walked away for minute. Came back and computer wouldn't wake up with keyboard or mouse. Attached the updated file. For some reason my minidumps are overwriting the older minidumps and I can't figure out why.

    Once again that crash was caused by Driver Verifier being ON and it detected special pool memory corruption caused by the display driver atikmpag.sys. Let's see how the system behaves once you have turned Driver Verifier off.

    Use the tutorial below to configure your mini-dump settings:
