Computer keeps turning itself on?

Specs: XP Pro SP2, Pentium 4 3.0 Ghz/ 1024 M

My computer's got an annoying habbit of turning itself on after a few minutes (varies) after i've switched it off. :S

I've had a look through the BIOS and can't see any settings that would cause it, Power on LAN and keyboard/mouse all disabled.

It hasn't got any other problems and runs fine beside this.

Anyone got any ideas?

Thank You!

Could be a spyware/virus issue have you scanned for both in safe mode?

i once had a sound card that made the computer always switch on, but it always switched back on a second after shut down completed.
Do you have a modem plugged into phone line - is a signal on phone line causing it (unplug phone line cable to try that).
Could be faulty power switch on front of computer where the contacts are only a hairs breadth apart and the slightest movement/vibration causes it to contact (try this by disconnecting those two wires from the motherboard)

Just a thought, but some motherboards have the option to power on the computer via keyboard or mouse. Might want to check that.

I'd try disconnectng any communication cables from the computer first. That would be LAN and Modem cables. If it still restarts, disconnect the keyboard and power down the PC. If it still restoarts, then power down again before it is fully off, remove the mouse. If it still does it get a priest to do an exorcism.

If it is not a WOL (Wake-On-LAN) issue, you may have a faulty PSU.

I once had an Intel 430/440 board that did that. I troubleshot that thing til I was blue in the face.

It was in fact, trouble in the motherboard. Either the bios was corrupt or the motherboard had an electrical problem.

I finally just powered it on/off through a switched strip.
