    Bad pool header?


    Got an BSOD i haven't gotten before earlier this day.
    It occured around the time i connected and disconnected a my Camera via USB i think.
    I think it was disconnected, and then randomly as i was looking away, then back it was in BSOD, if my memory serves right.

    Though not sure if that's to blame or something is unstable as my PC is overclocked, but it pretty much never crashes otherwise, so i want to confirm what the issue is as i can't reproduce it i think.

    Yes, BAD_POOL_HEADER.

    Do three things on an urgent Basis:

    1. Uninstall MBAM. Download a fresh copy of it and install it.
    Code:
    BugCheck 19, {3, ffffe001f61ac320, f61ac320, ffffe001f61ac320}
    
    *** WARNING: Unable to verify timestamp for mbam.sys
    *** ERROR: Module load completed but symbols could not be loaded for mbam.sys
    Probably caused by : Pool_Corruption ( nt!ExFreePool+cb6 )
    
    Followup:     Pool_corruption
    ---------
    2. Update windows to latest. Windows Update - Check for and Install in Windows 10 - Windows 10 Forums
    A non-up-to-datw windows is subject to various threads including security threats and BSODs.
    Your windows is ....
    Code:
    Windows 10 Kernel Version 10240 MP (4 procs) Free x64
    The latest version is 10586.

    3. Test your RAM modules for possible errors. Run memtest86+ for at least 8 consecutive passes.
    Code:
    BugCheck 109, {a3a01f5a74ec775e, b3b72be0c76ccab5, fffff80173a6d340, 1}
    
    Probably caused by : memory_corruption
    
    Followup:     memory_corruption
    ---------
    If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.
    Take a camera snap of the memtest86+ window before closing the program. Let us see it.

    Thanks for the clear explanations.

    Have done the Malwarebytes part.

    I don't understand why i have an old Windows 10 version though, there is no update?

    As for MemTest86+, i have run Prime95 90% Available RAM for over 12 Hours and some other stress testing to make sure it's all stable.
    But i will do such a test when i got time. How long do you think 8 passes will take for 8gb of RAM?

    Whatever may be the reason behind it, update it now.

    Prime95 tests the CPU, not the RAM.
    For 8 GB, it may take several hours. Better you run the test overnight.

    I can't update, there is no updated in Windows Update:S?

    Prime95 Blend should test RAM as well, but indeed it's not it's primary function.
    I will do a MemTest86+ test overnight when i can!

    If you cannot update windows at all, I would suggest you to get the latest Windows 7 ISO and perform a clean reinstall.

    If a windows install does not update, it is corrupt, and subject to fail and crash. It will be vulnerable to security threats, too.
