Solved Asus p7p55d-e pro won't boot after installing new PSU. Tags: Boot Motherboards Last response: March 15, 2014 7:28 PM in Motherboards Share Nathan Rocklein March 15, 2014 7:06:14 PM My old PSU (xfx 750) made a load pop and then died. I then installed a new PSU (cx 750) and get a green power light on the motherboard. When I go to boot, the fans spin for about half a second and then stop. Is my motherboard shot?
