I flashed my 360 months ago, played it alot, no problems. I have not used it in a while though. Yesterday I popped in a Backup of Forza 2. Raced a couple, and it froze. I shut it off and went to bed. Today I turn it on, it boots up loaded up until the main screen in Forza and froze again. I shut it off, and when i turned it back on it will not boot. The circle around the power flashes Red (I think only lights 1,3,4 but it may actually be all the lights). Any idea what could have happnened???
