Computer randomly starting
I built my friend a computer and loaded windows xp pro on it. Every time he shuts down the computer, after about five minutes the computer restarts by itself. I have flashed the bios, and turned off all the wake-up features in the bios. It makes three clicking noises before it actually starts up again, but I can't figure out what is making it restart. It has an ABIT AN8 mobo, 1gig ddr ram (2 sticks in slots 1 & 3), two ide hard drives, two dvd drives, and a nvidia geforce 6200 graphics card. I have the almost the exact same computer and I haven't had any of those problems. Any help would be greatly appreciated.
