if you download the driver from the manufacturer's site, then there isn't much risk.
Anyway, you should have the previous driver saved somewhere or on a CD , in case the new driver is worse.
Just download the new driver anywhere on your PC, such as "my documents" or even the desktop.
It should be a program, you'll just have to run it and follow the instructions.
That kind of problem is pretty common, it happens to me whenever I buy a new video card.
But it's strange that it only happens recently for you ...
