    It looks like there is something not quite right with your CPUID CPU-Z installation. A driver is triggering the crash:

    Code:
    FAILURE_BUCKET_ID:  AV_cpuz138_x64!unknown_function
    
    BUCKET_ID:  AV_cpuz138_x64!unknown_function
    
    PRIMARY_PROBLEM_CLASS:  AV_cpuz138_x64!unknown_function
    
    BugCheck A, {a67e78c, f, 1, fffff800064331a7}
    
    *** WARNING: Unable to verify timestamp for cpuz138_x64.sys
    *** ERROR: Module load completed but symbols could not be loaded for cpuz138_x64.sys
    *** WARNING: Unable to verify checksum for win32k.sys
    Probably caused by : cpuz138_x64.sys ( cpuz138_x64+2084 )
    Try reinstalling CPU-Z or uninstall it if you no longer use it.

    Unfortunately it appeared to happen again.

    Is there a specific tool that I should use to traverse the logs myself?

    It looks like it is the same driver so you are going to have to manually find the file and remove it. There must be an entry somewhere in the start-up sequence that calls for the driver to load.

    There is a useful program called Autoruns that you can use to find startup tasks on your PC and disable them.

    Here is the driver file location: cpuz138_x64.sys 26/02/2015 6:04:34 PM
    \??\C:\Users\Matt\AppData\Local\Temp\cpuz138\


    I use WinDBG to examine the mini-dump file created by the BSOD crash event. You can read up how to use it here.

    Thanks Phil!

    Found the culprit to be Corsair Link reinstalling the file and blocking deletion but got it all sorted now.

    Thanks for the tools and info, will keep an eye to see what happens after I install the latest version of Link
