So you mean it flashes everytime?
Btw, post a full parts list before we zero in on the problem.
I Plug the power cord into the wall and switch it on then switch the PC on at the power supply. I press the PC ON button then flashes once then nothing. I unplug everything then plug it in again and press the on button then flash on the LEDs like last time then nothing. Every single time I have turned it on it always flashes then nothing.
