I have noticed this type of noise when going into and exiting from Windows.  I
think that it is the monitor switching sync modes.  I have windows set up using
a high res super VGA driver (800X600).  When Windows is installed without the
high res driver, the noise does not occur.  It seems to be a normal function of
a dual frequency or multisync monitor.
