Dred...go back to your original drivers... read my post a few yup its a bit more detailed..kind of.
Good Luck
I did. thats what caused me to seek new drivers to start with.
I read on a tech forum soewhere from someone else having the same problem with a different game that Nvidia cards sometimes have issues with machines that use Corsair Ram.
Having bought 2 more gigs of kingston ram for my machine I removed ther one 512 corsair I had in there to use on my wifes machine. Thought that had been the answer. then the game locked up 3 times ina row the other day.
Seems very intermittent. I can go days without a hitch. Then 3 or more times in one night. Or 3 or 4 days in a row
