I believe I have a serious problem with my copy of Halo: 3. When I was playing an Xbox Live match some time ago, the graphics began to go fizzy and the menu had a long streak of lights across it. I ignored it for a few days, but eventually it got so bad I couldn't play anymore! A few days later I attempted to play again, but my xbox shut off. When I tried to turn it back on I got the e74 warning.
Well, I've sence had the problem fixed, and It works just fine, but when I play Halo: 3 I get the same problem as before, and the xbox gives me e74 for a few days. Do you have any idea why this might be happening? I got the game brand new, and there are no scratches on the disc.
