Okay, basically my PC will be switched on, and at any random time it might restart. DRIVER_IRQL_NOT_LESS_OR_EQUAL is all I can read on the bluescreen before it goes, it kinda only stays on for a split second. My minidump is attached. I've tried blowing all the dust out of my machine, and swapped my RAM sticks into another machine where they work fine. Any suggestions? Thanks.
