yep I was waiting on your update
I would leave driver verifier disabled because when new drivers are released you will get the BSOD issue until the driver has the WHQL signature assigned to it http://pcsupport.abo...uality-labs.htm
See what an Nvidea scan suggests for the video card http://www.nvidia.co...aspx?lang=en-us
I would leave all other drivers be for now and see how things go.
Just a FYI, driver updates are mostly released to address known issues so if you are not having the particular issue you should not install the driver as it can actually cause you the very same problems that it is intended to resolve.
You are welcome BTW
