well thats good to know, i got mine for christmas this year and bought an extra 2yr warranty after the microsoft 1yr. i love my 360 so farnever had problems with mine ... minus the first one I bought used that ALREADY had the RROD (and I knew it had the RROD).
Anyway the new gen of the 360 don't have the RROD problem anymore.
Or you could just send it away and a week later have it returned and working...The fix is simple. Simpler than installing a CPU i'd say. Check youtube, there is a three part video where the guy shows you how to do it and i've done it to 3 360's and its worked each time.
Yeah the updated dash blew the GPU's if they were already on their way out.Likely, and a lot of individuals with original release 360's are long out of warranty, with the extension microsoft gave out included. However, there is a report that after the mandatory dash update, this week I think, a bunch of 360's crapped out. Check tomshardware.com for information on that.
If the GPU has been damaged do to heat (melted) re-tightening the heat sink is just about as useful as bolting it to your nut sack.good luck!
youtube says its usually a gpu heat issue and you can re-tighten the sinks.
