So i got an GF4 MX420 and installed it. After i installed it everything was fine and i wen't to update my drivers to 40.72. after the installation finished and it restarted, i had no taskbar. I tried hititng the windows key and nothing happened. I tried going to control panel/appearance and themes and went to start menu and taskbar and nothing popped up. I was messing around and seen an option to roll back to previous installed driver. so i did that and now i still have no task bar. Help please im out of ideas.
