So I didn't know were else to put this, I think there's a xbox support section but I couldn't find it, sorry. But anyways onto the problem. About 20 minutes ago I went to gamestop and purchased gears of war 3. I got home plugged it in and i love it , but 5 minutes ago i was setting up a game of hoard to play with my friends and all of a sudden i got an error that said "This game cannot be authorized" I then got a 3 red ring and my xbox shut down. I then turned it back on it 3 red ringed again and then shut itself off. I turned it on again and it has been working correctly with 3 red rings but freezing occasionally. I then blew it out with an air compressor and its working correctly. My Xbox is First Run Halo 3 Limited Edition, no modifications.
