Its been at my dads house for a couple weeks without being played. We go to play it and in the middle of the game it goes to dashboard. It ejects the disk takes it back in and does it again repeatedly it shuts off and on by itself aswell and when you press the power button it just turns right back on. Only way to stop it is unplug the power cord. Its not the controllers because it does it even when there arn't any connected. HELP?
