    BSOD playing Overwatch, error L1C63x64.sys

    Hi all,
    I have been experiencing this BSOD: Driver IRQL Not Less or Equal, L1C63x64.sys for a few months now.
    When it happens, it is only when I am in the middle of gaming (Overwatch).
    After some research, I see that there are many of the same problems with my ethernet driver (Qualcomm Atheros AR8161). I have updated the driver via the Device Manager on my computer.
    I am hoping maybe there is a different fix other than having to replace my ethernet port/motherboard, because that seems like it is the next step.
    Thank you,

    You could look for a USB ethernet LAN adapter.

    Add a new PCI or PCE-E lan card and disable the onboard LAN. That should fix this problem.
