aparrently one 360 has had some artifacting problems, can be seen HERE possibly a fan died or heatsink was not put on correct, or maybe the xbox 360 doesnt have adequate cooling, or just a defective xbox?
edit: it was said that the artifacts were not present during video playback, but were there while in the menu, thats a little strange to me, because if it was a heat problem wouldnt it be there all the time?
