Windows 7 Ultimate 64-Bit
Irql bsod

Hi everyone,

I've been getting an IRQL driver BSOD for a few days now. I'm not too sure what driver is causing it because my WhoCrashed just says "Unknown".

My graphics, chipset, and BIOS are up to date.

Unfortunately, I can't upload the memory dump because its 400MB and 104MB in a .zip folder, but I can copy and paste what my WhoCrashed said.

Crash dump file:        C:\Windows\memory.dmp
Date/time:              8/9/2011 2:12:42 PM
Uptime:                 00:37:16
Bug check name:         IRQL_NOT_LESS_OR_EQUAL
Bug check code:         0xA

Bug check parm 2:       0x2
Bug check parm 3:       0x0
Bug check parm 4:       0xFFFFF80002CAC3EA

Bug check description:
This indicates that Microsoft Windows or a kernel-mode driver accessed paged memory at DISPATCH_LEVEL or above.

This appears to be a typical software driver bug and is not likely to be caused by a hardware problem. 
A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: Unknown .
Any help is very appreciated.
