I have an ATI VGA Wonder+ (the 1024 card) with 512k and a mouse plugged into
a no name 386-33 (Hawk motherboard) and connected to a Loop multiscan monitor.

There is a whistling sound emanating from the case. Ordinarily with the
other sounds coming from the power supply and diskdrive (maxtor-200),
I would ignore this sound as just normal machinery noise.  However, I have 
found that the frequency of this sound changes as the screen changes, and
even as the mouse is moved from one part of the screen into another.

Is this normal? Or, do I have something configured incorrectly?
Could this sound be caused by using the wrong software driver for a specific
program?  
Or could the whistling sound be coming  from some other device?

Thanks for any and all help.
