BSOD L1C63x64.sys driver

rawrrex · 16 Aug 2015

Hi, I am getting BSODs and the error message it gives is:

Driver_IRQL_NOT_LESS_OR_EQUAL(L1C63x64.sys)

I believe that is the Qualcomm Atheros Network driver, but mine is up to date to the last Windows8 compatible driver on the Atheros website. This leads me to believe it's a third party program causing the BSODs but I'm not familiar with reading the minidump files. I've attached the dump files and any help would be appreciated. Thanks a lot!

Hi, thanks for the reply. I have seen that thread, but my Qualcomm Atheros driver is up to date with the latest version compatible with Windows 8.1 (there are no Windows 10 downloads on their website), and I don't have BullGuard installed, so I don't think that thread is too applicable. Thanks though.

Hi Boozad,

Thanks for the response. My Qualcomm Atheros AR8171/8175 Gigabit Ethernet Controller driver is the latest one available for Windows 8, since they have nothing for Windows 10 yet.

I've uninstalled all of the Juniper programs to see. Hopefully that solves it. Thanks again!

The Qualcomm driver could have been a false positive caused by the Juniper driver, hopefully that's the case. Keep us posted.

Hi, i have the same problem that is causing a lot of BSODs every day.

I know that one of the problems is the Qualcomm Atheros drive, but there is not any driver for Windows 10 in the Atheros web site.
I have noticed in other threads, that you have found additional programs that are causing the BSODs.
I hope that you are going to do the same here.

Thanks a lot for your time.
