For what its worth... I'm guessing its a driver that was causing it to crash. I downgraded to XP 32bit and its very stable. I'll just wait for Windows 7 to go to production I guess to upgrade.
I'm still having trouble that during the POST sequence it takes about 30sec polling the USB headers, but I'm not sure what the problem is there. Even when I was running the memory at 800mhz and had everything else set via auto on the mboard it was causing problems
