Download latest nvidia drivers from nvidia.com.
Install latest directX 9/10 drivers. Make sure that there are no stuff running in the background. Be sure that your virus free and don't have malwares, etc these will freeze up your game.

Also be extremely sure whether your PC is over heating. If your graphics card is overheating, you could experience all sorts of weird things happening. Check your computer whether its well ventilated clear off dust and that your fans as well as your GPUs fan is working properly!
