You say the hard disks are actually working / spinning... Are they
really spinning? And... working... do you hear the heads move? Or do you
see the hard disk LEDs blinking? If they do blink... that means the
machine is booting (which would explain why no POST beeps).

Have you checked that you haven't, mistakenly, unplugged the monitor? Or
turned it off? Or broken the monitor cable after years of twisting and
bending it? Have you tried plugging the monitor into a different
machine? I've had my monitor power supply die on me like that... and
before I figured why there was nothing on the screen, it took me some
time. :)
