I just finished the external build of my computer and I tried using the screwdriver to turn it on by touching the pins. Nothing happens at all. then I tried connecting the power plug from my case and clicking the power on the case, still nothing happens. I did everything carefully and got everything plugged in. I see the green led light on the motherboard when I flip the power supply switch. I had my friend on webcam look at my pc and he's trying to figure out what's wrong.
