Re: no power to computer? motherboard or power supply?
I burned 2 PS in the past, and an indication that it was the PS was that when starting up the computer there was a short glimpse and then nothing. The first time it happened, the technician told me that the power supply will (should) blow up before anything else; in other works it will cut off before damaging your computer. When the second PS burned, I immediately knew cause it did exactly the same thing. Note, the green light on the motherboard stayed ON even tough the PS was out.
