Windows 10: BSOD while downloading files, L1C63x64.sys Solved

    BSOD while downloading files, L1C63x64.sys


    Have tried finding a solution on the internet but so far no luck.. I keep getting BSOD when downloading (and only when downloading) files. I have attached the dump files.

    Everything seems to point at my network adapter driver. Which is from Atheros. Alas they do not have drivers for Windows 10. Anything I can do here? I already tried driver verifier and it doesn't seem to be a 3rd party problem. Also did a memory check and it's not that either..

    Thanks for any help.

    EDIT: Uploaded the correct zip as per the posting instructions. Was in too much of a hurry it seems.

    Hi Jeri,

    Welcome to the 10forums.

    Please remove BullGuard, it is the cause of the crashes.
    It tries to communicate with the internet with its firewall, that is why the network driver is marked as the cause.

    Problem seems to have been solved after uninstalling Bullguard. Thread marked as solved.
