You should be able to update your driver for the graphics card. If you can, open the Nvidia control panel. Then, if you look around in the menu, you should see something along the lines of "Check for new update". Just click that and it should lead you along to update the driver. If you can't find the Nvidia control panel, or for some reason the "Check for update" isn't working, you can go to this link to get updated drivers for Nvidia graphics cards. They even have an auto-detect graphics card feature.
