I would download the newest drivers from amd.com directly and install them. If that didn't work, I would open the window, take the computer and throw it as far as I could :P
(That's why I have to buy a new computer every 2 years I guess)
But in the first place a gamer never buys an all-in-one PC. We either buy a console or build the system ourselves and then mod it until it looks like an alien spaceship or a taru-head.
