I have a Xbox 360 premium, it is not hacked or modded in any way. Just recently it started freezing up and random time, sometime on boot up, sometimes in the dash, sometimes during game play, sometimes while booting up a game, after playing an hour, ect. It's random. It happened shortly after the latest COD4 update, I have no error lights, all is green and no third party attachments. I?ve tried different game disks with the same result. i have cleared the hdd's cache, i have tried removing the hdd and still the same. I CAN watch a DVD from start to finish with no problems. (weird I know) so would you say that it over heating and fixing to get the RROD, I've had that once before and had to have M$ replace it.
