I've had Live for a while, and I bought Halo 3 when it came out, but yesterday for some odd reason, when I play Halo 3 for say about 10 minutes or so, the screen goes all red and fuzzy (like a scrambled tv channel), and then the screen just goes black, but you can get some audio, but only for a bit (abuot another 30 sec.). The game itself is in perfect condition, no scratches or anything. When I take the game out, the main xbox dashboard works fine SOMETIMES. Sometimes it too will remain blank with no audio. Any ideas anyone?
