Hello there. Well, I built my computer in early 2008, and have done periodic updates ever since. Just a few days ago, I purchased a new 1TB hard drive and 64 bit windows 7. On a side note, I don't think this has anything to do with the problem. I was playing All Points Bulletin and the computer randomly turned off. Upon repowering the PC, the CPU fan did not light up or spin up at all, but the power button did work, as it's routed through the motherboard. On the other hand, the motherboard speaker never went off upon boot, and nothing came up on display. Was I just unlucky that my motherboard crapped out when I bought something new? or could something have caused this? Thanks.
