Hey all;

A friend handed me her dead computer to see if I could get it up and
running. When you turn it on, nothing happens. No lights, no fans, nothing.
So, I figure it's either the power supply or the motherboard (at least).

I want to test the PS first, before just replacing it. It is an ATX 300w
supply. I connected an 8 ohm 10W resistor from red (+5v) to black (ground)
and turned it on, but nothing happened. I then turned it on and shorted the
green wire to ground, but still nothing. Can I assume the PS is dead, or is
there something else I should be doing?

Thanks

On more than one occasion, I've seen it be simply the 110/220 input
voltage switch.

I think sometimes they get moved partially out of position when the case
is grasped just right [just wrong?] and pulled out from under a desk.

Worth not overlooking.
