Ok, well a few days ago my computer randomly went blue screen when i was playing a game.... and i Rebooted it more then once... So then i figured it might be faulty ram. So pulled out the sticks of ram, 1 by 1 testing each of them, So it turns out the last one can make it so the blue screen doesnt come for about 10-15 minutes after i have logged on.. removing the others still had blue screen come after about 1-2 mins or less after i signed into my computer. Should i just go buy a new piece for the one that lasts 10-15 mins? Whats the problem?
