I just built a new rig and when I click on turn off computer it acts as if it were shutting down but actually restarts instead.

Gigabyte GA 81865GME - 775
Intel D 915
Ultra Xfinity 500 watt psu
Sapphire Radeon 9600 Pro
Coolermaster Centurion 532 case
Ultra pc 3200 1 gig ram
Seagate 7200.9 160GB HDD
Win XP Pro SP2

It did this from the first time I booted up so I reformatted HDD and reinstalled OS. No other Apps have been installed. Only updated drivers for hardware. Any help would be appreciated.
