Thanks for the reply, I've been running memtest for 2 and a half hours and it says I have about 84000 errors on about 1.5 passes. I assume that's what you meant by an obvious problem?
My PC will not stop BSODing and I can't figure out why. At first I thought it was the antivirus but I've since got a new one and it's still doing it. I have a few dump files attached that might help.
