Did you clear the CMOS, by disconnecting from the wall and display, then removing the CMOS battery from the board, holding the power button down for 30 seconds and then replacing the CMOS battery after 30 mins?

You might want to follow through steps outlined in your motherboard's manual;

psu is good an tested
How did you come to this conclusion? How old is the PSU?
