In my experience, all of these resets are a waste of time. Basically the graphics card will flake out a couple of time and then its just completely dead. My buddy went through all of the resets, battery swaps, as I did and in both cases a new motherboard was the only fix. If his computer was subject to the nVIDIA issue, they didn't know that or didn't tell him.
