Ok so I was playing a quick match and all of a sudden my power supply on my xbox goes red, ive seen this happen before on my old system but never on my new model. So I unplug then plug it back in again and set up a match and the same thing happens. So im thinking it's a heat issue I let it cool for a few hours and try again but it happens again. So in assuming that it was just a power supply problem I went and bought a new one, got it home, same problem! But then I put on Netflix, watched a few long movies in hi def and no problems....??? So then I play cod 2 for like 2 hours.......... No problem. Gears3 for another hour......... No problem. I go back to bf3 15 minutes into a tdm boom powers off! Seriously am I just insane? But I've been testing this for the last few days and the only time my system shuts down is during bf3. So any feedback or solution, or even if you've just seen this happen let me know.
