Back about a month ago my 360 ended up with the 3 red lights again. Its been out of warranty & i had fixed with the penny fix earlier this year. So this i chose to do the xclamp method. We took the heat sinks off cleaned up the cpu/gpu applied new arctic silver ,and all that jazz. Well it didnt work so i let my dad piss with it after 2 failed attempts by myself. He got it to work ,or so we thought. It now turns on ,and then shortly after it turns on the fans slowly start to roar then after several minutes ,or once you got to load a game which ever happens first the system shuts down with 2 red lights. I read something on one site about how it could possibly be as simple as the heat sinks arent fastened down tight enough. Could he have not got it tight enough so its causing the error? Any ideas. If its something that stupid i rather do that than spend another 200 for a new one.
