The last couple days my 360 has been freezing up on me (checked screen and total lockup). I'm writing this just in case someone else runs into similar issues...
It is amazing how many articles about freezing are available online via your preferred search engine. I've had this system almost 2 years now with very few problems to-date.
some theories -
1. Overheating system - i purchased a cooling system (the 3 fan variety), while that didn't help me directly i'm sure it is part of the issue and i plan on keeping it. My system and power supply were moved into a more enclosed tv stand a few months ago; that + it being cold in MN and the furnace running might also have an effect.
2. About the same time I moved TV stands, i changed from the standard R W Y cable to the R G B cable. I read someplace online that increasing from 720 to 1080 (or whatever the common dpis are) makes the system work harder and can contribute to overheating as well...so tonight i moved back to the standard component R W Y cable. we'll see how that goes.
3. The Microsoft support link below said to perform 'maintenance' by following some arcane settings...i did that and it _may_ have helped?
4. I had a couple of stalled downloads of demo games. i deleted all of those from the hard drive as well..
i'm considering moving the whole thing to the basement which should help it stay cool...i just don't want to move my TV down there too :)
