So I've installed the correct driver as prescribed by one of the members off the NVidia forums. It comes to a part, half-way into the installation that it freezes and you still get that laggy graphics. Now in device driver it says that "Video Controller" it says that "Drivers for this device is not installed. (Code 28)" And I have a choice to "reinstall driver" which is confusing... also have a few choices to update, rollback and uninstall driver. It's been an issue for the past 3 months, although it has worked once when I attempted to install a game - and mysteriuously enabled me to "enable driver". Thanks a lot if you can help.
