The latest nVidia drivers are working for me but I noticed it added support for 3D stereoscopic Drivers and a new running process. Being a bit anal
about what I have running in the background,I checked it out.
I found a process named nvSCPAPISvr.exe running after the update to 186 and a service called NVIDIA Stereoscopic 3D Driver Service which was set to auto. Unless you are planning on going 3D wwwLink I suggest setting it to manual or disabling it.
It may or may not be related but it's something to look at. I turned it on and off a few times,and saw no difference aside from one instance of showing 122,000+ handles on my system monitor,which dropped down it's normal range (approx 15,000-20,000)after I shut 3D off again.
Trying The_Goo's suggestion would be the next step.
