I've had this 360 for about 3 weeks now and have been playing it moderately. Its very well ventilated but this past day or two it has frozen a total of 5 times.....once on COD2 and the other 4 times just this morning on Texas Hold 'em XBLA game in which caused me to lose a substantial amount of cash each time. I still have the receipt for it from Wal-Mart and i'm wondering, should I take it back or what? Like has this happened to any of you guys? Oh and also it runs real loud when its been on for more than an hour at a time.
