i know your prob, i hope. take out your card delete the drivers, nvidia has a bad prob with updating, you need to install the latest version from scratch, then put your card back in. if this doesnt help i cant say much, but to buy all nvidia products from evga, they are the only ones with superior cust serv and can get you thru the nightmare
How do you update the drivers without the card in the machine?
I've not had a problem updating Nvidia drivers in the last couple of years, so I'm calling BS on your statement.
