Yes, if for some reason the updating didn't seem to "take", i.e., still getting the same problems, try the following:
1. Download Driver Cleaner Pro or Driver Sweeper (both have free versions; make sure the version will work with your OS) to your desktop screen and install.
2. Download the latest diver(s) for your video card but don't install them.
3. Uninstall your video card drivers and reboot your PC into Safe Mode. Run Driver Cleaner Pro or Driver Sweeper but ONLY for the video card drivers. I had someone use it on their chipset drivers! If it doesn't find any video card drivers that is quite okay; just leave all other drivers alone.
4. Reboot and install new video card drivers.
