Question: how
can a power supply make noise when it fails in the manner
described above?
normally one of the components is trying to do something with the power,
but it can't. sort of like when you short a wall transformer and it starts
to hum. Another example is how some of the old computer screens or TV's
sometimes put a high-pitched whistle.
