Hi I'm a nooby at installing hardware and in reasently installed a new psu and graphics card. When I put all connectors in all I got was a green light on the motherboard. I took everything out and tested just the power, 1 stick of ram but still nothing happened only green light on mobo so there must be power going to the mobo but nothing happens and no post either. Took it to a repair shop the guy done the same and still gave a green light and nothing else. My mobo is a H81M-PLUS. Psu is Corsair cx 550m. My graphics is asus strix geforce gtx 960. Any help would be greatly appreciated
