Usual causes:  Kernel mode driver, System Service, BIOS, Windows, Virus scanner, Backup tool, compatibility
This bugcheck indicates that device driver has attempted to access a invalid memory address, or perform an instruction at a inappropriate IRQL level.

From the call stack, the thread was placed in a wait state, to allow the APC to called, and allow a driver to complete it's I/O request, which is why the IRQL level was pushed up to DISPATCH_LEVEL. The IRQL level was lowered, so when a driver wanted to page some data into memory, it was a illegal operation.

1: kd> !irql
Debugger saved IRQL for processor 0x1 -- 2 (DISPATCH_LEVEL)
Now, although noticed that the Flink and Blink addresses for the linked list were invalid, therefore I went and checked the instruction, and it said that there was some pool corruption.

Sorry for the really long post, but I think we may be dealing with some kind of driver issue here. I would keep Driver Verifier running, some people even recommend 36 hours.

I switched out the drivers, played a couple games, and saw no degradation in performance. I still have the driver verifier on, but haven't had another crash yet.

I'm fine with long posts. They are most informative. Thank you for the help so far.

Just to keep you updated, I've had the driver verifier on for about 45 hours now, and I haven't received a crash since the first one. Maybe it was the video driver, since it was the only one not from Toshiba, but I'm not sure. Should I turn off driver verifier at this point?

Run a scan with Malwarebytes . Update the definitions before you do a Full Scan .

Have you ran a memory test running memtest86+ ?

Vistaking, all of that is covered in the first post. Multiple scans with MBAM, MSE and WDO found no viruses. Memtest86+ ran for 7 passes with no errors.

Turn off the Driver verifier . See how the PC is running if you get any crashes (BSOD) upload using the Tool

Disable Driver Verifier as already suggested, and you may run this command in an elevated command prompt, to make sure Driver Verifier has been disabled:

verifier /query

I turned off driver verifier when Vista said to. The computer seems to be running well at the moment. I'm gonna give it some time before marking the thread as solved. I repped bluerobot. Would have done it for Vista too but it says I need to spread it around more first.
