So I bought an 360 a little over a week ago and have been playing it pretty frequently. Ive played through Assassins Creed Brotherhood, Trenched Dead Rising Case Zero, and a decent amount of Halo matchmaking. Then I downloaded Undead Nightmare. I threw in the Red Dead disk to start playing and as soon as the game started up my xbox started running really loud. It ran silent up until then. I didnt give it much thought though since I was playing for a while befor then and thought the fan might just be kicking in. After about a half hour of play I heard a sound like a spinning disk rubbing against something it shouldnt. I stopped the game and took out the disk, it was fine. My question is should I be worried about this, it only seems to happen when I play Red Dead, anyone else run into this problem. I have one of the new 4gigs by the by. thanks!
