IRQL-Not_Less_Or_Equal BSOD?

I have been all over the place trying to figure this one out, I keep getting random BSODs, literally there is no warning or specific software that triggers them. At first I suspected 2x1GB dimms but I tested the bejesus out of them and it passed on 3 full passes in extended test mode and no problems. I recently downgraded to XP Pro (Vista sucks nuts) and my computer supports IDE emulation so I figured this was a possibility but more likely I assume it is running virtual disc programs causing a IRQ conflict with my already present optical device. Any clues that will save me the time from actually writing down the offending addresses and going through the 500 devices in hardware manager would be appreciated.

Update:

As it turns out, running XP using IDE mode is the likely culprit as BIOS enabled IDE emulation is supposedly very unreliable, acer was supposed to include a rollback cd for xp pro as well as a pre-install driver to allow xp to handle laptop SATA, if anyone has the disk images for these missing files or a slipstream ISO let me know where yah got it.

    Some hardware device that does not want to play fair with Windows... My top of the line Canon MP960 generates one when Vista boots on my system.... if I leave it unplug (USB unplugged that is...) then I never see the message again...

    I also once got the message in XP from a USB wireless adapter made by Belkin...
