Computer Not Shutting Down
(Click here to view the original thread with full colors/images)

Hi. I'm not sure when this started nor what triggered its happening but lately when I go to shut down the computer Windows XP shuts it down but the computer itself does not turn off, but rather cuts power then starts back up again (as if I pressed the reset button).
Any ideas?
Thanks
OS: Windows XP Pro
Motherboard: Asus A7N8X Deluxe
CPU: Athlon XP2400+ (2.0 mhz)
RAM: 2x512mb
GPU: nVidia 6600GT

Weird. Have you tried running Avast, McAfee or AVG Free to make sure you don't have trojans or viruses? Some pretty strange stuff is out there. You might also want to run a program like Registry Mechanic to see if your registry has been changed in come way that is causing it to do that. It's a long shot. Most of the trojans I've heard about cause your computer to shut itself down instead of making it refuse to shut down properly, but who knows? Maybe someone's gotten really, really bored out there!
Next, if this doesn't fix the problem you might try a repair install of the operating system.
Last: One time it turned out to be a hardware problem on one of my much older machines. It turned out to be a lower quality mobo (which I see you don't have, by the way) that had so many solder balls that most manufacturers would have flunked it on the quality control tests. In your case I'd look for any bare wires or loose screws that may be in contact with the mobo and causing a short somewhere. You might want to check the switches on your casing too. I've heard of really dirty switches being shorted out by metalic dust. $5 for a can of compressed air is a good investment.

I think its a hardware problem, possibly with the PSU. If you have any spare ones lying around, try swapping them. To shut down your computer, just hold the power button once windows shuts down, the turn off the power on the PSU.

It could even just be dirt in the PSU! The power supply seems to always be the place it builds up the most. Otherwise, just do as Matt.modica has suggested.
