    High Pitched whine from i7

      I have a new Dell Studio 1558 with an i7 740QM processor.  From new, my wife and I  have detected an intermittent extremely high pitched whine/wwhistle - so  high that if we are not facing in the right direction we can't hear  it.  I did some research and found out that it was not unheard of.  So I  called Dell and after a lengthy discussion. persuaded them to send  someone out to change the processor.  It was fine for a few days then  started again.  Now, here's the interesting bit.  It only happens when I  run Internet Explorer 8!!  Why would the processor behave differently for  a particular browser?  I would love someone "in the know" to explain  what is happening and whether there is a cure.
