Welcome to the forum.
Have you gone to the nVidia Web site, plugged in your card's model, and your OS, and looked to see if you do have the latest driver?
I would not trust the OS, or any driver utility, to tell you if you do have the latest. Manually check on the nVidia Web site, vs the installed driver version.
What OS are you running, and what is the number and date of the installed video driver?
