    BSOD while using the internet. error (L1C63x64.sys)


    When using my vpn I get the BSOD.

    Driver_IRQL_NOT_LESS_OR_EQUAL(L1C63x64.sys) My cpu says it is the Qualcomm Atheros Network driver, I made sure it was updated still happens. I would appreciate if someone can look at the log posted below I am lost at the moment with this

    Thank you

    Hi trainman81,

    Welcome to the 10forums.

    Daemon tools, Alcohol 120% and Power Archiver Pro uses SCSI Pass Through Direct (SPTD), which is a well known cause for BSOD's.
    Please remove Daemon Tools and run the SPTD pass through remover.
    1. Uninstall Daemon Tools
    2. Download the SPTD standalone installer and follow these steps:
      • Double click the executable to open it
      • Click on the button shown below

    If the button is grayed out, like in the image, there is no more SPTD installation on your system, and you can close the window

    AVG is trying to request data from the internet, which is why the network driver is marked as the cause.

    It is further recommended to check your Qualcomm network driver for updates, its driver is not supported for Windows 10.

    Tried above Still get BSOD


    I took Daeman Tools off my cpu along with avg.

    I restarted cpu. logged into my vpn. Used mozilla within 20 mins it crashed two times. first after taking Daeman off than after uninstalling AVG I attached the dump file with the two new crashes today.

    Could i buy a separate new Ethernet card. Since i have updated Quallcom Atheros Drivers But they do not support win 10 I did get this same blue screen in win7

    I purchased a d-link Ethernet card. I have not gotten the BSOD since. i appreciate your help.. i can assume it was the driver for my ethernet port on my motherboard since it works now. well worth the 12$

    thank you for your time and effort
