I upgraded Ati device drivers to catalyst 5.8 and my three monitors are working fine. However everytime I restart the computer hardware wizard prompts me to install software for multiple unknown devices. Under device manager/other devices, 6 unknown devices are listed. I have tried diabling and uninstalling them but they keep coming back.

Any advice will be greatly appreciated.
