Okay here is the problem. My PC just started freezing up on me. I would have to shut it off by the power switch in back.(Power and reset switches non-responsive) If I tried to turn it on right away it wouldn't reach boot. But if i waited longer it would boot halfway, then stop. The longer I waited the longer it stood on without error. It kept on freezing in less time. Finally I went to a friend of mines house, it ran flawless for 2 days! I thought, "It's fixed?" Brought it home, froze. Then it just woudn't boot at all. I found there was no internal speaker, so i put one in.(Beep codes) The beep codes said CPU ERROR. I then took out CPU, it looked okay. Can anyone tell me what is wrong? I really don't want to buy a new one, then see it doesn't work either. Thank You.
