are you plugging in the cords correctly? lol.. it's a problem i had are you plugging in hopefully an hdmi cord to your monitor to your gpu itself and not your motherboard? it's not the motherboard or the gpu clearly. what i would do because 550w is perfectly fine for that build it's more than enough is i'd pull out the gpu and then plug in the hdmi cord into your motherboard and use the onboard graphics in the i5 and then wire that to your monitor and see if that works. if that works then i really don't know what to say lol..
