I just built a new system and is having major problems. It wont turn on at all. When I press the power button on my case, nothing happens, pressing the power button on the motherboard has the same effect. Everything is connected correctly. I even unplugged everything and connected again. But one weird thing tho, when I unplug the power cable from the wall and plug it in and then hit the power button on the case, the power button flases red once and then nothing. I even tried switching out the ram. please help

this is what i have
