Ok Ive been working on this computer. It was having random restart issues. I believe the registry was corrupt. SO fine I cna restore it, heres where it starts to get interesting. When I would run the windows repair off of the XP disc, the system would blue screen when trying to get into the repair section. So I was going to repair XP, but when I go to install the repair, I hit enter and the system blue screens. So I shut it off and now I hit the power button and it does nothing. I figured it was the button so I plugged the reset button into the power button spot on the mobo and still wont come. What do you think? power supply?

this one has me at a loss.
