-PC was stable for a long period until recently
-Generally reports IRQL_NOT_LESS_OR_EQUAL but many others seen (MEMORY_MANAGEMENT, PAGE_FAULT_IN_NONPAGED_AREA, KMODE_EXCEPTION_NOT_HANDLED etc)
-I removed a stick, crashes stopped and so thought it was bad RAM and bought more
-As soon as I installed the new RAM (in whatever combination), it started crashing again
-Memtest ran 1 pass fine
-chckdsk ran fine
-It crashes in Safe mode, but much less than in normal mode (so stressing the RAM?)
-I have 2 ATI graphics cards in crossfire, so I tried unplugging each to see if one was faulty and still bluescreened
-I booted off the Win7 DVD and it also froze (once). It also crashes on the window loading screen, and I have done a system restore to the earliest possible point, so I don't think it's drivers.
Yeah, I've seen enough crashes to last a lifetime. At this point it always happens within minutes of loading up Win7, and more regularly before it even gets to that. See attached for computer info (AMD phenom II, 8gigs RAM and it gets worse if I add more)
Could it be the PSU? Mobo? How can I diagnose further? These are expensive, I want to be as sure as possible that's the issue before I buy a new one (sadly I have none spare). It's generally well exposed and not that dusty - I guess I can try one more vacuum.
