OK, I have this old computer that I just found. I know pretty much nothing about it, other then that the previous owner has a fresh install of XP on it. It has a P4 at 1.8 GHZ, and an ASUS P4s533-MX mobo in it. It has 1gb of ram as well. There can't be any virus's on it, cuz it's never been connected to the net. OK, so heres the problem. Safemode works fine, but when I try to boot normally, it gets to the desktop fine, and then after a couple of seconds on the desktop it just beeps from the CPU speaker, and restarts. No clue why. If anyone could help me out here, that would be awesome. Thanks.
