James1;
There are many items that are fixed in each WHQL release of nVidia's drivers. Some are related to hardware issues (like failures, crashes, reboots, etc.). Some are related to updates in the rendering and shader portions of the GPU or multiple card (SLI) support. A review of the "Release Notes", shows just how many issues are addressed in JUST THIS release of the drivers:

We ALL want the CUDA cores issue resolved, but since many of us currently have systems strong enough to turn off "Hardware Acceleration", the workaround of turning off the cores is a workable solution (on a temporary basis).
I would suggest that if your card supports the newest WHQL drivers (306.97), install them and disable the CUDA cores in nVidia Control Panel. Sadly, my GTX465 card does NOT support the new WHQL drivers, but I am running 306.23 very successfully with both PD10 and PD11. There are different cards supported for 32BIT and 64BIT, so use the nvidia page to be sure your OS, Language and Card are supported:

Using this method, you will find that WHQL 301.xx is supported by SOME cards, but NOT ALL. Additionally, the link will assure you get the right ones for your Card!!
EDIT: OK, last edit for this post (I promise): Nvidia and Microsoft do not recommend or support "rollback" of Graphic Drivers. You should use "Clean installation" option (under CUSTOM during installation), or COMPLETELY remove drivers using "Add or Remove Programs". See page 35 on the "Release Notes" Document ABOVE for a detailed explanation from Nvidia.
Notice I say WHQL a lot? I do NOT recommend BETA drivers..they are BETA for a reason, and most of us just don't NEED the "bleeding edge" to get what we want!!
Just a suggestion, I am NOT nVidia or Cyberlink..just a poor user trying to share my thoughts without getting punched for my efforts!!
