Extra ram doesn't help if the game doesn't need it, 2 GB should be enough but you might try
quitting any other programs in case one of them was using a ton of ram.
Your problem sounds like it's the video card driver though, I had no luck at all with nvidia 182.06,
182.08 was better and is playable but I'm still having trouble. I'm happy with the ones greyblade
recommended above, I can finally alt-tab to windows desktop w/o crashing! I have a 8800 GTS 320 mb,
these have worked for at least a couple people, but couldn't find these listed in nvidias 'driver archive'.
Here's the links to them at nvidia.
Nvidia 180.48 XP 32bit(typical xp)
Nvidia 180.48 XP 64bit
Nvidia 180.48 Vista 32bit
Nvidia 180.48 Vista 64bit
