so, my xbox just automatically shut off and gave me 2 red rings for overheating. (first time ever.) I turned it off and back on and it loaded up no prob---of course i then turned it off to let it cool down. question: is it basically a forgone conclusion that either a) it is going to now always overheat after being on for an hour or so? b) i will get the full-blown death in my near future? I appreciate any light that can be shined upon this.
