So I have this NVidia card I stopped using because of all these issues, but I fixed most of them and found workarounds. Mostly what I want to do is play games and use Blender. well yesterday, I installed the latest drivers for my card which is an NVidia 9800 GTX, and everything was working perfect, the next day when I turned my computer on, everything was acting as if I never installed the drivers, it was all slow and stuff. The only way to fix it is to reinstall the drivers, and it sucks to do it all the time, also, with my ATI, reinstalling the drivers eventually stopped fixing my problem, and I don't want the same to happen to this one. What should I do to fix this?

Did you uninstall the old video drivers before installing the new ones?

Check device manager to see if there are any problematic drivers installed.
Also, check to see if any onboard cards you may have are active and overriding the new card.
