Drivers for my laptop Asus X55U with amd Raedon graphics for win 7 64bit are not at all supporting. Screen is keep on flickering and its very odd to use browsers and graphical tools.
I would try a fresh installation of the latest AMD graphics drivers provided by your laptop manufacturer. Please use the AMD Clean Uninstall Utility to remove the old AMD drivers.
