I recently updated my older style XBOX 360, and have been having issues with the console powering down during play. I've already had this console serviced for the RRoD, and it was working perfectly before the update. When it shuts off, the power brick's light is red. I have to disconnect it, then plug it back in for the console to restart, then it happens all over again. There are no RRoD lights on the console itself. Does anyone else have this problem? It just doesn't seem coincidental that this problem started after I updated to the new dashboard.
