SO, i got this computer from a freind of mine, he got a virus and took the whole thing apart. I put it back together to the best of my ability, and everything works. but everytime i press the power button, it beeps when the hdd led pops on it runs for about a minute after that and then shuts down. the mother board has a digital read-out thing on it and it says 7F as the computer shuts down. If anyone knows what the 7F means, or where i can read up on the mother board its self it would be greatly appreciated. If you need more specs on the comp dont hesitate to ask.
