I am getting BSOD at iregular intervals with the same error code "IRQL_NOT_LESS_OR_EQUAL" caused by L1C63x64.sys, which is a driver for

"Qualcomm Atheros AR8171/8175 PCI-E Gigabit Ethernet Controller (NDIS 6.30)".


this seems to be a recurring theme with this driver but i havent been able to find my hardware ids in the other threads.

hardware ids

PCI\VEN_1969&DEV_10A1&SUBSYS_10A11849&REV_10


PCI\VEN_1969&DEV_10A1&SUBSYS_10A11849

PCI\VEN_1969&DEV_10A1&CC_020000

PCI\VEN_1969&DEV_10A1&CC_0200


Current driver version in my desktop is 2.1.0.21 and was published 7.16.2013. ive tried to do an automatic update to the driver, run windows update, tried to find a newer driver on the motherboards website, and other online sources, but havent been able to find something specific to this (can confirm from motherboard manual that part is the ar8171)


thanks in advance for any help
