WMI Provider Host constantly disrupting performance of my CPU, especially when music is playing.


The WMI Provider Host always flares up to about 30% of CPU usage after about 10 minutes on.  When it does, if I'm playing any music it slows the computer down so the music becomes jerky and distorted and the computer runs slowly.  I don't have any 3rd party virus programs, and haven't installed many programs, so don't understand why it does this.

I have a Windows 8 Desktop machine and mostly use it for internet and playing music, so this is particularly annoying when it happens.

I am not technically minded, so does anyone have a simple solution for a technophobe?!
