The only thing I can think of would be to try and replace the psu with one with more watts. I would think 480 would be plenty but I cant think of any other reason it would just restart like that. How many hard drives do you have? If you have more than one, try disconnecting one and see if the same thing happens. You could also disconnect any of your optical drives and see if it restarts. If it doesnt restart when you have any of your drives disconnected, you probably need a new power supply. Good luck.
