    KMODE EXCEPTION HANDLED (bwcW8X64.SYS) BSOD on Windows 8.1


    I've been getting this BSOD a couple times of day and haven't been able to fix it. I believe its a problem with the Killer Network drivers but I updated to latest drivers provided from my motherboards website: MSI. They happen randomly and it doesn't occur when I'm doing something specific. I uploaded my minidump files.

    Hi Ski3high & Welcome to the forums ^_^,

    I have analysed your dump files and below has been provided an analysis of the same for informative purposes :-
    Code:

    ffffd000`67decb00 ffffe001`396002b8 0xffffe001`3969ed58
    ffffd000`67decb08 fffff801`838f8c67 0xffffe001`396002b8
    ffffd000`67decb10 ffffe001`396003b0 bwcW8x64+0x2c67
    ffffd000`67decb18 ffffe001`396002b8 0xffffe001`396003b0

    ffffd000`67decb28 00000000`00000001 0xffffe001`3a8cdd20
    ffffd000`67decb30 00000000`00001000 0x1
    ffffd000`67decb38 00000000`00000000 0x1000
    So the Killer Network Driver caused a Divide Error which caused the BugCheck.
    There is a workaround for this specific problem. Try this below -

    I cant be too certain but this seemed to have helped. I haven't received a BSOD all day.

    Unfortunately, I've gotten about 3 BSODs. I'm almost certain it is a problem with the killer e2200 drivers. I get my drivers straight from MSI website. Ive tried getting them from qualcomm instead since they seem to regularly update their drivers but it wouldn't recognize my Killer nic. I'm completely out of ideas at this point.

    Could you please upload a freshly generated SF Diagnostic ZIP File?

    Did you follow the workaround? What was it's result?

    Okay its been about 2 days and I'm almost certain that, the new method in that forum has performed the trick. I also had issues with the stability with some of my games and people reported that the e2200 killer drivers were in conflict with some games. This problem has since been fixed.
