Ok so I have an xbox 360 which is around 3 years old, bought it pre-flashed and havn't had a problem with it since. I havn't updated the firmware since I bought it as it has never had a problem playing any game no matter how new. But just yesterday it started displaying 3 red lights, but not all the time... It only happens occasionally which doesn't seem like a terminal problem, so maybe it is something to do with the power supply as I've read elsewhere? Also sometimes when it does boot up, it loads for a few seconds then there is a faint beep from the console and the picture freezes. Thanks to anyone that can shed some light on the problem.
