I've had this xbox for about a year. It's been pretty wonderful but i've noticed the sounds on booting up an using the disc tray would disappear from time to time. BEFORE YOU TELL ME TO UNPLUG IT AND PLUG IT BACK IN THEN REBOOT IT, I've done that multiple times and it's no use. I feel cheated by my xbox as i paid the original retail price (close to 450) for this thing because of the sounds and now it doesn't work. It makes me reconsider buying any future Microsoft products.
