Ms Tech support for Xbox sucks! If you do get the red rings, just go to game stop and buy another 360. Yes! I know what I said sounds insane to spend more money but when my Brother sent in his 360 to MS, they sent him 3 broken 360's! Yup, and it took 6 weeks for each system to get back to us! And Ms denies this, but I have actually proof of a HDD failure causing only the Bungie games not to work (will be making the YouTube vid soon) honestly the 360 is a poorly made system, don't expect the system to last as long as our old Nintendo systems did.
Ohh yeah:
360 is great for Halo 3 but the system is just poor Pc game ports. If you have the money I rec you invest in a good gaming PC instead. Cod 4 plays better on the Pc than the 360 anyday!
