Yeah I recall fiddling with the power supply some time ago but that didn't fix anything. It's probably just a console hardware issue. I guess if I'm really aching to play like Soul Calibur or something else I'll go to like Geek Squad (do they do repairs I thought they did) /contact Microsoft or just buy a new one. Thanks for the help and advice though!
Personally, I haven't played a lot of Halo to really have a say, I was afraid of playing certain games back then, namely multiplayer, in lieu of sucking really badly or something silly. I know at the very least a majority of those who play with inverted controls spawned from Halo, right? Anyway I really enjoyed Halo Reach's sandbox feature in particular. I hope it pleases the Halo fans at the very least, but I've heard some good things and bad things about 5 that are a bit too vague/broad to mention.
