It has 2 Power Sockets on it On being the standard ATX connector and another being the additional 4 pin connector. You need to plug both in for this to work.

If you have a AGP Video Card you'll also most likely have turned off the on board Video in BIOS so that may be why you are not getting any pictures.

Try changing the jumper setting to Clear on the BIOS which should be a 3 pin header with pins 1 & 2 shorted out you need to change the Jumper to Pins 2 & 3 and disconnect the Mains Lead to clear the 5 V DC line that is always on with any ATX Power Supply.

You could also look carefully at the Capacitors near the CPU these look like little tins with a plastic covering standing on their ends, Look for any bulging or leaking if one of these is bad the M'Board is shot. But because several M'Boards had shoddy Electrolytic Capacitors on them they can sometimes be covered by a [b]Recall Notice[/b] where the maker will replace the M'Board for free. They will generally speaking either swap the M'Board over or repair your existing one which requires it to be sent back to Taiwan and repaired takes about 8 to 12 weeks depending on the chain of supply that it has to go through.
