Got my 16 year old son x-box360 for x-mas. 6 days later he is playing a game and it locks up. He turns the console off, turns it back on and gets a message: "An x-box 360 hard drive must be attached to play original x-box games" 1. The x-box 360 hard drive IS attached. 2. It is NOT an original game, but an x-box 360 game. Where do I start?
