Help with my 360

[Bob]

yes i'm back, i've been reading up on everything too, hope our lili comes back soon. but i'm havin problems with my xbox 360 and knowing quite a few people here are video game players, i was wondering who could help me. my 360 likes to overheat all of a sudden. when i turn it on, it used to play for 15 mins then freeze up. now it will just flash me the 3 red rings of overheatedness. i don't want to deal with microsoft, and it doesn't seem to be a ventilation problem, i've pretty much dangled the system in mid-air while playing to see if it would turn on. thanks all
