Have you checked to see that your drivers are up to date?

Also check if your graphics card keeps cool enough.

Yeah, probably. In most cases you can find more recent drivers online than the ones that come with the card.

It is best to update the drivers every few months, if the game you are playing was released after 02,2006 there is a possibility it was programmed to take advantage of the capabilities of the newest nvidia drivers.
