If you notice a problem after installation, use a restore point to get back. Don’t do what I did and suspect everything BUT the driver. It isn’t worth the time
In this case. it stopped the sleep function of my PC.
Also, before installing ATI drivers, or anything major really, make a restore point. I had to go back to the 17th..
More problems.. the restoration cobbled my ESET 5 installation. I will get around to re-installing it soon.
On the plus side, it deleted a bunch of LG drivers which did nothing beneficial towards connecting my LG phone to the computer. You win some, you lose some.
