I tried to update my AMD radeon hd 7770 graphics card, now it says there is no driver installed. When I tried to update to the new software my computer restarted half way throw. Now it says my driver is up to date, but it also says I don't have a driver installed. It wont let me roll back to previous updates either. Does anyone know how to fix this or revert back to an older update?
