    BSOD DPC_WATCHDOG_VIOLATION happens randomly


    Hi this has been happening to me every time I use windows 8 and has never happened to me in windows 7.
    I have a:
    XFX nForce 790i Ultra Mobo
    Intel Q6600 Core 2 Quad
    8GB Patriot Viper DDR3 Ram (2x4GB)
    Nvidia 8600GTS Video Card
    Asus Xonar Essence STX Sound Card
    Haupaugge 1850 TV Tuner
    OCZ Agility 3 240GB SSD
    Samsung 750 SATA HD

    I hope someone can help me out and analyze my minidump files and help me figure out whats wrong. Thank you!

    7, 8 whatever


    Hi there. Remove Avast! in safe mode with tool from them, in safe mode. Reboot, then set Windows Defender and Windows Firewall services to Automatic. Start them.

    Update:

    HCW85BDA HCW85BDA.sys Tue Jul 14 16:46:46 2009 (4A5CEEB6)
    cmudaxp cmudaxp.sys Tue Nov 18 05:09:34 2008 (4922945E)

    Do those things in any order you want. If they stop happening (as if before Avast! removal to suppose) - then you can keep Avast installed instead, but it is the most likely culprit here. Cmudaxp is a very close 2nd most likely.

    Okay so I uninstalled Avast using its own tool in safe mode.

    As for those two files I believe they are for my Hauppauge tv tuner and Asus Sound card and I've updated them to 2011 drivers, though I don't think that there are drivers specifically for windows 8 yet.

    Will post further if the BSOD comes back. Thank you so much for your help and quick reply!
