I posted this before, in the OS section, about my bluscreens, well yesterday they came back and I couldn't both into windows, this is after a fresh install. Luckily I had my UBCD and poped it in. Memory gave no errors after 10+hours in Memtest or in 10+ hours of Windows memory Diagnostic. Although both the Prime95 ad the lucfier Burn in test shows errors. Could this be my cpu biting the dust or my mobo? which should I replace first?
