Download DriverMax and have it scan your system. It will open their website with all the out of date drivers you can update. With the free version you can update only 2 drivers per day so if you have a lot of them it will take a few days to get everything updated. I have been using it for about 4 months now and like it better then any other utility out there for keeping my drivers up to date.
I would suggest specifically downloading and letting Drivermax update that video drive.
Second of all please get a screenshot of the list it gives you so I can go through it with you and make sure you get all the drivers in order that will maximize your updates.
