System instantly reboots after shut down

[cmonkedo]

Hi I have a bit of a weird one I just finished building a system and with all current drivers or drivers shipped with motherboard/video card my system will not simply turn off. It goes through the windows xp shutdown procedure and the system turns off ie fans stop spinning but then it instantly turns back on and boots. The system is an amd 6000+, a gigabyte GA-M61PME-S2P AM2/AM2+, and 2GB DDR2 800 Kingston Dual channel, and nvidia geforce 8400 video card. any insight would be appreciated.

edit: the system is off a clean xp sp2 installation

I would check your bios for "power up on PCI" (or any other bus for that matter) to make sure its not a screwy card.

Also make sure reboot on crash is unchecked, in case you are crashing during a shutdown step. <-- though if thats the issue you may want to hunt it down.

What drivers did you install? Seems more a software problem than hardware...
