    Windows 10 several unexpected shut downs


    Hi all, attached is my PC. I am having a reoccurring problem with my PC where it displays a blue screen after giving me no indication of a problem. One error message in the blue screen is "kmode exception_not handled (bwcW8x64.sys)".
    When I look at my crash logs and try to look for a solution, it searches and can't find a solution.
    I am a designer and use revit, photoshop, sketchup, autocad, etc. I don't think my software is causing the problem, because I've had a crash even with only my email open.

    Thanks for reading!

    Mark

    Hi corbwho,

    Welcome to the 10forums :)

    The driver bwcW8x64.sys is part of the Qualcomm Atheros PerformanceSuite program, please update/reinstall/remove it.
    Code:
    6: kd> lmvm bwcW8x64
    Browse full module list
    start             end                 module name
    fffff800`dac70000 fffff800`dadc5000   bwcW8x64 T (no symbols)           
        Loaded symbol image file: bwcW8x64.sys
        Image path: \SystemRoot\system32\DRIVERS\bwcW8x64.sys
        Image name: bwcW8x64.sys

    Really appreciate your quick response axe0. I have done your suggestion and should know by the end of the week if I don't have a BSOD. After that, I'll mark this as the solution.
    Again, I really appreciate your help.

    I have had 4 additional crashes since your initial suggestion. I have attached another file for review. Again, it's without warning, no fan running, not alot of applications open, etc. Any other ideas on what may be causing this?
    Thanks

    You'll need to upload the file again, it is empty.

    Same cause, same driver, same driver date.
    It seems updating/reinstalling doesn't help so I suggest that you remove this Qualcomm Atheros PerformanceSuite program.
