Hi, I'm glitched with the coolrunners since 3-4 months, never had problems. I boot the xbox this afternoon, no problem at all. I started playing Mass Effect 3 (DVD 2). The xbox hangs. So I press power off manually, and restart.... no glitching anymore...???? Even with XELL, I see the coolrunner do its job by the lights and heard the little sound of the "reset", but nothing at all... IS it a silent update of MS?? Xbox-Slim, Coolrunner, Dash 14699
