Driver_IRQL_NOT_LEE_OR_Equal (l1c63x64.sys)

   I have been getting the following BSOD error almost once a day of late:
Your PC ran into a problem and needs to restart. We're just collecting some info, and then we'll restart for you.

If you'd like to know more, you can search online for this error:
Driver_IRQL_NOT_LEE_OR_Equal (l1c63x64.sys)

My first thought was to update the driver but when I attempted this it states that the driver is current. The version is 21.0.21, but the date on the driver is 07/16/13.

These are the stats on my system:
Motherboard: ASRock FM2A88X Extreme6+
Processor: AMD A10-6800K APU with Radeon HD Graphics, AMD64 Family  21 Model 19 Stepping 1
Processor Count: 4
RAM: 16304 MB
Graphics Card: NVIDIA GeForce GTX 1050Ti, -1 Mb
Hard Drives: C: 465 GB, D: 1862 GB, E: 930 GB, F: 3725 GB, G: 4657 GB, I: 931 GB
OS Version: Microsoft Windows 8.1 Pro, 64 bit
Antivirus: ESET Smart Security

Any ideas or thoughts on what I should try next would be greatly appreciated!

Thank you in advance

	Hi, Problem : the version 2.1.0.21 is the last version for Win8x. Did you do / receive any update (drivers, system ...) , Did you try to remove / install again the Atheros driver ?

	Brucer - I cannot upgrade to Windows 10, which I abhor, due to the fact that one of the programs I must use, via a VPN, will not work properly under Windows 10... Prodiff - That references Lenova...but would the driver be the same? Nightbird - I get all updates via Windows Update, and have tried to find the driver, but ASRock does not show this driver at all, and I am ambivalent about installing a driver meant for another brand/system... I think it is the VPN I am having to work with, but I cannot find any reference to it and this BSOD error message. Edited by SarcasticWit - 27 Sep 2017 at 9:25am
