Windows 7: cpu usage 100%

cpu usage 100%

Hi,
Often when watching a film or using an audio app like live or cubase my laptop locks up and the cpu meter shows a solid 100%! I can slowly get into task manager but no processes show high cpu usage. all I can do is a cold boot but even then sometimes it restarts at 100%.
Any help would be much appreciated.

It is a dell latitude e6400 win 7ultimate 32 bit less than a year old.

Run a full anti virus scan
Download and run malwarebytes full scan
If they are both negative, post a pic of your task manager that shows the process showing usage

Hi Rich, sorry for late reply-credit ran out!
I ran malwarebytes, avg, spybot- all clean but still the cpu usage goes up to 100% and stays there with no programs running , in task manager processes there is nothing using more than 5 or 10% and the total of the cpu column is about 15 or 20% but at the bottom of the window it says cpu 100% (I couldn't get a snapshot to post)
It never does this when I am running linux from its own partition, only in windows.

Now I have processes from all users showing and audiodg.exe is using 40%
Can I disable 'Microsoft HD Sound Driver for HDMI' or fix it?
I'm not sure if I have ATI GPU or even what one is!
