    Hi. This is my first post so please let me know if I should have provided any other relevant information. I have been getting random BSOD over the last few months on my desktop PC. I am running windows 8.1. The error message I receive is a win32K.sys error. When I look into this further using Reliability Monitor the error codes that occur are always different. I have attached the dmp file for the latest BSOD incident. Please let me know if I can include any more details or information. Thanks!

    1. Welcome to Tech Support Guy


    2. How long please have you had that Corsair Vengeance ram in - I think you have two sticks of 4GB each


    3. Its SPD serial presence detect is 1333 are you running it at that please or have you overclocked eg changed ram settings to run at 1600. If you have please return to default settings


    4. AVG - if it is the free version uninstall it and use Windows defender
    If it is the paid for version and presuming you can re-install then for testing purposes please uninstall and use Windows defender - for the time being


    5. Also for testing purposes disconnect all external devices except keyboard, mouse and monitor


    Please post back when you have done this and also include in your post please - the make and full model of the computer if branded
    I know from the dump that it has
    ASUSTeK Computer INC.
    Maximus IV GENE-Z
    Rev 1.xx

    Hi. Thanks for the repy. Whilst I was following these instructions I experienced 8 BSOD crashes and now have started up in safe mode with networking. I have attached the dmp files for all of these crashes if that is useful.


    1. Thanks!
    2. Yes I do have 2 x 4GB RAM. I’ve had this ram for about 2.5-3 years
    3. As I’m the only person who uses this computer as far as I’m aware the ram settings have not been changed. They are at default setting.
    4. I have uninstalled AVG.
    5. I have disconnected everything except my power over Ethernet.


    I built this PC myself so here are the components.
    Windows 8.1 Pro 64-Bit
    Intel®Core™ i7-2600K CPU @ 3.4GHz
    2x 4GB corsair vengeance RAM
    Motherboard – Maximus IV GENE-Z
    Graphics – AMD Radeon HD 6850

    Please let me know if I can provide any other information and thanks!

    One of those crashes was caused by your graphics driver
    X64_0x3B_atikmdag+725178


    I suggest you download this
    Display Driver ver. 14.10.1006
    http://support.amd.com/en-us/download/desktop?os=Windows%208.1%20-%2064#amd-catalyst-packages
    SAVE it do NOT install it at this stage


    I then suggest you go Control Panel Programs and features - uninstall any reference to AMD or ATI graphics
    REBOOT
    Windows will then use a generic driver for the graphics


    Then install from the saved download


    See how you go with that please and without AVG - other of the crashes do possibly tend to suggest other problems, but lets see how we are when you have that new graphics driver installed please

    Have installed the new graphics driver as suggested. Used my computer for a few hours and didn't experience a crash. Will let you know how things go over the next few days. Thanks!

    These were related to hardware (probably memory) I would run memtest to test the memory and driver verifier to check for an underlying driver issue

    ------------------


    EXCEPTION_CODE: (NTSTATUS) 0xc0000005 - The instruction at 0x%08lx referenced memory at 0x%08lx. The memory could not be %s.

    These crashes were related to memory corruption (probably caused by a driver).

    Please run these tests to verify your memory and find which driver is causing the problem.



    If you are overclocking (pushing the components beyond their design) you should revert to default at least until the crashing is solved. If you don't know what it is you probably are not overclocking.

    Since it is more likely to be a driver please run verifier first.


    1-Driver verifier (for complete directions see our wiki here)

    If verifier does not find the issue we can move on to this.
    2-Memtest. (You can read more about running memtest here)


    If you cannot boot after enabling verifier reboot into safe mode

    Good news -maybe




    will wait to hear from you - IMHO you can leave further troubleshooting until and IF you do experience a crash
    As I have said -
    these crash analysis are not an exact science and the fact that memory corruption occurred may simply mean that the driver was responsible - it does not by any means definitely or even on the balance of probabilities indicate faulty ram.

    Unfortunately I have had a few crashes in the last few days. I have attached the dmp files associated with these crashed. Not sure if it is relevant but my display has been going black for a few seconds before returning, randomly a few times every hour or so during use.

    The latest you have sent two on the 17 and ne on the 18 July are all memory corruption - most likely caused by a driver
    On one of the crashes it is most certainly this
    X64_0xD5_atikmdag+c7dbb


    that atikmdag is the video driver


    Did you follow the procedure for installing
    You must uninstall the old first and reboot, it is not sufficient just to install the new.

    ADDITONALLY go control panel, devices and printers - right click your computer icon and click device installation settings
    Ensure it is NOT set to allow Microsoft to install drivers for your hardware with Windows updates

    TRY again please with the driver and that setting, in case Windows updates have changed it again

    If YOU then experience another crash we will look further at OTHER possible causes.
    Not knowing how long it is since you built the computer - is all clean of dust inside and as my colleague said -
    run memtest
    there are 8 to 10 tests in each pass and you need to run two complete passes.
    It is best tested on ONE stick at a time

    Yes I did follow the recommended procedure. I have re-installed the graphics driver again as instructed in addition to disabling windows driver update. I clean my comp out on a regular basis so there isn't much dust build up. I am currently running memory test individually on both of sticks as per the instructions...I will let you know the results of this in the next 24 hours or so. Thanks for your help!
