Turn off the spontaneously reboot option. It's under My Computer, Properties, Advanced (tab), Startup and Recovery, and uncheck the box that says Automatically restart.

I always get the 0x000000D1 error. I upgraded my VIA chipset drivers, and it works FINE now! It's not a problem with Xolox, it's my friggin chipset.
