I have a very similar problem, with using the Nvidia display drivers with Windows XP, but during normal use of the pc, ie not playing games or using any heavy graphics processing.

I have tried some similar methods to resolve the problem. I've also re-installed Windows XP, uninstalled and reinstalled lots of versions of the Nvidia drivers, and upgraded DirectX.

However removing the graphics acceleration has been the only method that has reduced the crashes, but even that no longer works. The driver crashes as soon as the pc is switched on, and Windows brings up the error screen that allows the selection of safe mode, vga mode, etc. An infinite loop error entry is sometimes written to the event log, but mostly no entry is made.
