  2. BSOD - driver_irql_not_less_or_equal (l1c63x64.sys)

    Hi Seung,

    Sorry for the inconvenience caused by BSOD - driver_irql_not_less_or_equal (l1c63x64.sys).

    Please let us know the make/model of your computer.

    The L1C63x64.sys is the Atheros LAN driver and I would suggest to uninstall and reinstall the Atheros LAN driver but install the latest Atheros LAN driver by visiting the manufacture's website and avoid using any LAN driver available though Windows Update.

    However the problem could also be with any VPN software and other software so make sure you have the latest version of each of these software.

    If the errors continue uninstall the VPN software and check if the issue persist.

    Hope this helps. Get back to us for further queries for BSOD - driver_irql_not_less_or_equal (l1c63x64.sys). We are happy to help!

    BSOD: driver_irql_not_less_or_equal (e2xw10x64.sys)


    My girlfriend brought a BSOD to my attention while she was on my computer today. She was watching YouTube videos and playing some games on Facebook Apps when she got the BSOD. The information she gave me was directly from the screenshot of the error information
    which is stated below.


    ERROR: e2xw10x64.sys

    Any idea of what caused this?

    driver_irql_not_less_or_equal ndis.sys BSOD



    I just started getting BSODs with the error "DRIVER_IRQL_NOT_LESS_OR_EQUAL in L1C634x64.sys". I've tried updating the driver on my 'Qualcomm Atheros AR8131 PCI-E Gigabit Ethernet Controller (NDIS 6.30)", both automatically and via the Atheros website. They only show WIN8 drivers, and I have the latest version.

    I'm not sure if other drivers or software are causing the conflict with the atheros driver. I attach the logs in hopes you can help troubleshoot.
