Daehawk, I'm not sure how powerful your PC is, but when a 90nm triple core chip floats on its contacts due to heat, I doubt it's because it's failing at doing it's job... It's not the horses fault if the rider can't stay in the saddle.
I just wish they'd repair/replace all the bad parts in their pile of "dead" 360s, fix em right and offer a free swap program with all-new boards and proper cooling. Then recycle the ones they get in, etc, etc.
I'd like to see them do this before the blockbuster season... b'cuz my PC ain't up to snuff.
