Heres the problem im having. I had let a buddy of mine use a computer that i was no longer using. It was working fine when he took it. He had it about two weeks then he called me and said he was having problems with the computer. The PC will turn on and go through start up when it gets to the desktop it restarts. You can only see the desktop a split second. Then right before it restarts a blue screen flashes with alot of stuff typed on it but it doesnt stay on long enough to read it. There are very few times when the desktop does stay up. When this happens i get a error that says (Missing C/Programs) any help on this certainly appreciated.....Its a presario 5330us pentium 4 if that helps.
