Powersupply beeps onces

[jblenox]

I have a evo blue 750 PS and when I try to turn it on I get a beep and then nothing I have unplugged it then replugged it and still no joy. Any clues for the group

Is the PSU plugged into the motherboard? It has to be connected to the board before it will turn on. Either that, or you have to jumper the green and black wire on the 24 pin connector.
