So I decided I needed to buy a new PC, so I got all my parts, and picked them up. I'd built a PC before, but I consulted several guides and got similar answers through each of my steps. So I've got everything plugged in, but when I turn on the power supply, and press the on button...nothing happens. Regardless of if I press the power button or not, lights on the GFX card and mother board turn on. I'm stuck, anyone got any suggestions?
