Right when I began booting-up my XBox360 to start the updates, it started acting wierd. Turns out that the overheating issue has finally taken it's toll, and I now have a semi burned-out console.
After discussing the overheating issue with Microsoft, they finally agreed to cover the repairs under warranty (the agent kept insisting they only had responsibility for 90-days).
So my XBox360 fails the day I attempt to download the updates, then I almost can't get it repaired under warranty (even though the overheating is a widely known issue). Quite a bit of bummers in one day...
By the way, I actively suggest users give this XBox360
cooling solution from Nyko a looksee... Thumbs-up!
