    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?

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