    BSOD CRITICAL_PROCESS_DIED randomly.


    I started having this problem after installing Skyrim recently.
    I tried recovering to before the installation but the BSOD's still were occurring.
    I then decided to clean install windows 8.1 and all the drivers (havent got round to the sound card driver yet though) and the BSOD is still happening.

    Anyone have any ideas?

    Without a better dump it's difficult to say what the cause is.
    The exception code is scrambled, it's meaningless, so we don't even have a clue at why it happened.
    Event the critical process is different, csrss.exe and wininit.exe are both being terminated in different dumps.

    Could you get us a full memory dump?

    Sure, how do I do that?

    Go the Start
    Right click My Computer
    Select Properties
    Click Advanced system settings
    Click on the Advanced tab
    Select Settings under Startup and Recovery
    Then under Write debugging information select Complete memory dump.

    Once a dump is created go to:

    Code:
    C:\Windows\memory.dmp
    Copy the file to the desktop, zip it up and upload it to a file sharing site like Onedrive. After the upload is done post the download link in your next reply.

    That's not a full memory dump, they're located in C:\Windows\MEMORY.dmp.
    This is a minidump, please follow the instructions again.

    This is your actual stack. The actual error was "EXCEPTION_IN_PAGE_ERROR: The thread tried to access a page that was not present, and the system was unable to load the page.", which caused the stack problem - when an image inpage error happens, the exception checking in RtlpSearchFunctionTable will end up consuming the stack (like you see here) until it faults out eventually (and then the process hosting this thread crashes). In this case, because it's a critical process (csrss), Windows bugchecks.

    Looks like C: went bye-bye here somehow. Note that I also looked for it in the global object table, and there's no references for C:, but they exist for D: and E: - meaning it's likely that C: is gone somehow, so nothing can be paged in from the disk. Either the disk went bad, or the driver made it disappear (looks like the standard Intel ICH controller, so not likely). The Intel drivers could be updated, though, as these are pretty old.

    It's probably time to start checking the HDD (s) in the system for SMART, at the least, and update the Intel storage, management engine, and chipset drivers with the latest from either ASUS or Intel, whichever is newer (they look to be potentially the same). Make sure you have the latest BIOS for that board as well (looks like September 2014). Your C: drive should *never* just disappear...
