100% CPU usage - according to HP Insight

[Twinkie3]

HP Pavilion a4316 - Win 7 Home Ed.  6 GB Mem - 1T hard dr.  The last 4 days I have received an alert from Norton Insight:  "Info, High CPU usage by: windows audio device graph isolation, Detected, no action required."  Process ID5240 CPU 100% of at least one CPU.- Source File:  audiodg.exe

Is this serious?   I download very few apps or programs.  I did upgrade my Norton Internet Security around the end of Feb. 2012, but this problem just started about 4 days ago. 

Any help would be appreciated.  Twinkie

I have a new Hp Pavilion win 7 home premium, ugraded to 8GB memory, because it would freeze up all of the time, brand new. Had to buy the mem cards extra$ now that problem is fixed, but I have Norton also, and get the same High Cpu usage, never had any problems though, I just ignore it.

Thanks for response.  I'll just ignore it too.
