    Bsod dpc_watchdog violation


    It's been less than 2 days since I upgraded from Windows 7 to Windows 10 and I already got hit by this BSOD twice.
    I searched on the web for solution and everything that I found is related to drivers outdated but I'm certain that all my drivers are updated. Can anyone help me solve this please?

    BSOD DPC_Watchdog Violation

    The issue appears to be the nvstor.sys :

    BugCheck 133, {0, 501, 500, 0}

    *** WARNING: Unable to verify timestamp for nvstor.sys

    *** ERROR: Module load completed but symbols could not be loaded for nvstor.sys

    Probably caused by : nvstor.sys ( nvstor+7468 )

    The nvstor.sys is the NVIDIA storage driver and had been known to cause blue screen errors in the Anniversary Update such as in the following topic:

    https://answers.microsoft.com/en-us/windows/forum/windows_10-performance/dpcwatchdogviolaton-windows-10-1607/64d349e0-1b5d-43d0-8115-0a2bb5d2bf29?page=1

    Can you check what versions of the nvstor.sys are available on the system:

    In the Device Manager can you right-click the first "NVIDIA nForce Serial ATA Controller" > Update Driver Software > Browse my computer for driver software > Let me pick from a list of device drivers on my computer

    With "Show compatible hardware" being checked what is listed under "Model"?

    What versions of the NVIDIA driver are listed?

    In the Device manager the "NVIDIA nForce Serial ATA Controller" may be located under "Storage controllers" or it may be located under "IDE ATA/ATAPI controllers".

    Also the Driver Verifier appears to be enabled and you should at this time disable the Driver Verifier:

    Windows Key + R > type verifier.exe in the "Open" box > OK > Delete existing settings > Finish

    Your Atheros AR5B91 wireless network adapter driver has been flagged. It's old and needs updating, check here for an updated version.

    I went to that website and I couldn't find anything to update my driver. Is this website reliable and trust worthy to download the driver?

    Yeah that should be fine, that Qualcomm site is a nightmare to navigate isn't it? Let us know how you go.

    Just tell me one more thing, should I download the Windows 7 or Windows 8 driver? There's no Windows 10 driver currently available and I'm unsure which one should I download. Previously I was on Windows 7 so that one would be recommended right?

    Personally I'd try the 8 version, you can always uninstall and try the 7 version if that one doesn't play nice.
