Windows 10: BSOD Issue with driver brynhildr.sys

It has been awhile that I have been having BSOD issues and finally decided to track them down, so event viewer pointed at Battle.net.exe as the cause, Blizzards gaming app. After that crash I activated Driver Verifier and in less than a couple of hours got the crash again while trying to open the Battle.net app. Driver verifier pointed to the faulty driver named brynhildr.sys, I couldn't find much on this driver other than it's related to Call of Duty's Anti Cheat drivers? I have uninstalled the Battle.net app and games I had on the system in hopes that it works better next time I install them

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- atikmpag.sys

This is most likely due to an installation/upgrade error with ATI driver's. I suggest doing DriveSweeper and the following:

• Drivesweeper all drivers & in Safe Mode
• Unistall all drivers that aren't used in DriveSweeper (CCC Profiler Updates, MSI AfterBurner, anything related to ATI that use's it's drivers.)
• After you do this, the first thing you need to do is go into Device Manager and Unistall your ATI Drivers

Once your done, restart the PC and then try installing the latest drivers.


I had several issues with this in the past, but I overcame it with logical reasoning and whenever I have a driver issue, I just use these steps and I always overcome the problem.

Best of luck! *Toast :toast:

 

wdf01000.sys and ntoskrnl.exe BSOD

I'm on Windows 10, 64bit

Basically, whenever I try to update my LPC controller through Device Manager, BSOD with WDF_VIOLATION occurs (culprit being wdf01000.sys)

So I try to use the driver verifier to see which driver is causing the BSOD, but then it causes BSOD (cultprit being ntoskrnl.exe)

Have no idea which driver is causing them

Please help!
