Just update to the latest driver.
When I do it, I tend to download the new drivers to the desktop, make a restore point, uninstall (don't use delete) the old drivers, restart and then install the new drivers from the download on the desktop.
You will then be prompted for a second restart.
I have found in the past that Catalyst Control Centre sometimes gets upset if you just use the update driver facility.
Windows sometimes whinges that it has found new drivers when it restarts (can't remember if that is the case with AMD) but don't let it do that - you want to install the latest drivers from the AMD site, which are on your desktop.
