Just for the record, I was having major problems with the DHZer0point drivers for Nforce 8443 where it was locking up the PC and also CTD with that stupid error if I stayed in the tower for a while.
The driver version corresponded to Forceware 84.43. I updated to 84.66 (DHZer0point 8466) and haven't had any problems.
Skuzzy has stated before that he only recommends the 61.77 NVidia drivers, and I had a lot of problems with most of the 7x and 8x drivers.
