I had a bit of a problem with the latest GeForce 320.49 driver. It sometimes crashed and recovered a few times. On one instance it played havoc with the mouse arrow graphics. Using the Nvidia GeForce Experience panel I selected to add beta drivers as an update option. Running on the 326.80 beta driver I've had no problems so far. The HD audio driver seems to be OK.
