BSOD @ random times, DRIVER_IRQL_NOT_LESS_OR_EQUAL, L1C63x64.sys

It's not always L1C63x64.sys, it has also shown NETIO.SYS but only once. I have not seen consistency in activity during crashes, it's happened idling, downloading, playing a game.

I've seen errors with this driver linked to the Atheros driver or a VPN (I have both a work and personal that have not had any issues), but as far as I can tell those drivers are up to date. The atheros site is down and all I see are "unofficial" driver sites.

Hopefully the issue is easy for you all to pinpoint! Any help is much appreciated. System info in profile.

Cheers~

Hello and welcome to TenForums :)

Your most recent BSOD indicates that you have Driver Verifier running and it has identified ScpVBus.sys which is usually associated with Scarlet.Crush Productions Scp Virtual Bus Driver. It is dated 2013 so there may be an update.

Please do not continue to run with Driver Verifier as it puts too much stress on your system.

The only additional information I could extract was related to a driver jnprns.sys which is a Juniper Network driver. Are you aware of any updates for this? The current driver is dated 30/10/2014.

Code:

ffffc081`87aa5fa8  fffff80d`95344801Unable to load image \SystemRoot\system32\DRIVERS\jnprns.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for jnprns.sys
*** ERROR: Module load completed but symbols could not be loaded for jnprns.sys
 jnprns+0x4801

Hm, that's for a work VPN. Looking into it, there was an update to one of its components 2 days before the first crash. I've uninstalled everything for now to test. If it seems stable, I'll reinstall from the newest version of that VPN software and see.

Had another rash of these BSODs at random times - the juniper driver has been uninstalled for a while, so I guess that eliminates that. If these still point to scarlet crush used in DS4Windows, I guess I will try to uninstall it since there aren't any updates.

Uploaded dump attached. What do you think?

most recent bsod is from 20.02.:

Code:

As u can see Juniper is running. Please update or roll back those driver:
