    Windows 11 BSOD Error: DRIVER_IRQL_NOT_LESS_OR_EQUAL What failed: portcls.sys.


    Hello, I am having a problem whenever I open a certain application Discord I get a BSOD with the error: DRIVER_IRQL_NOT_LESS_OR_EQUALWhat failed: portcls.sys.I have tried reinstalling the application, and it still crashes my computer. Booting Windows 11 in safe mode does result in the program opening with no errors, so I assume it is a system problem, however I do not have the technical capability to isolate what is causing the issue.I zipped my mini dump files C:\Windows\Minidump to here: https://drive.google.com/file/d/1q-mBW5KBGiDcTKRr1fI2eOW6y5fcKj3y/view?usp=sharingAny advice or assis

    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!

    При включении компьютера выскакивает ошибка bsod driver_irql_not_less_or_equal rtf64x64.sys Так же она может появится во время игры. Я переустновил виндовс с 11 на 10. Все равно не помогло, в чем проблема?
