2 computers in 4 months. See, PC's have a major advantage over other consumer electronics - you can assemble everything yourself. I can't believe, with all due respect, that your motherboard, CPU, video card and RAM modules died at the same time. It's easier (and cheaper) to diagnose the system components, buy replacements for the failed elements. Moreover - I am almost 100% sure that your disk drives are alive. Have you tried to connect them to another PC as external disks and check their condition?
I apologize for the off-topic.
