How to fix svchost.exe from using ~20% CPU all the time?

Hi everyone/AMD Support,

I have an AMD Radeon HD 6310 running Windows 7 32bit with Catalyst 12.3 driver.

The problem I've having is that svchost.exe is using ~20% CPU all the time.  The svchost is hosting Power, PlugPlay, and DcomLaunch.

When I launch ProcessMonitor it gets inundated with registry accessing from the svchost process to the point of about 20,000+ entries per second repeating over and over like below, yes that is not a typo twenty thousand+ per second.

I've read on another forum that disabling enhancements for audio will fix it as the device is testing the hardware for compatibility for audio enhancements just in case you want to use them but this does not resolve the problem.

Any ideas on how to stop it as it is causing audio glitching and jerky video playback, as well as heating up the unit when it should be idle?

Kind regards, Tim.
