Hey, as a follow up I went to Best Buy this morning and got the exact same motherboard and 30 minutes later the PC was up and running. So the problem was indeed the first motherboard. Sucks that I lost 2 days on this thing but oh well. I really appreciate the help.

Ok I'm going to return the motherboard and get a new one tomorrow. Thanks to both of you.

Well I know for sure that the GPU works but I can't test the CPU at all. The paper clip test worked on the PSU and when I used the "self test" button from an older PSU it turned on all the fans and lights. I don't know much about this stuff but I imagine the JPF1 pins or the circuitry around it could be broken. The thing I'm still not sure about is whether it's the case or the motherboard that is broken. If you guys think it's the motherboard for sure than I will return it.

Thanks for your reply. I did what you said and plugged in the GPU and connected a display. I also re-seated the CPU and put the cooler in the correct rotation. I made sure the PSU is connected to the wall plug and that it's turned on but I still get nothing when I press the power button on the case. Not even a sound or a slight fan spin. The motherboard is sitting on a box and the things from the case that I've plugged are: SATA cable, power switch, audio, case fan and USB3.

Things I tried: - paper clip test on 24 pin power connector, this made the PSU fan spin - removed one ram stick - disconnected case fan - removed GPU and network card - disconnected case power cable (the one with just 2 pins) and tried touching the corresponding pins on the motherboard with a screwdriver - tried a very old PSU and got the same result. Except that this older PSU had a "self test" button which made all 3 fans spin and lit up the motherboard and case lights, not sure what this means. - took the motherboard out of the case, same thing Basically the problem seems to either come from the case power button/cable or the JFP1 pins on the motherboard and I need to know which one is the problem so I can return it. From what I've seen most similar problems come from people putting the power switch on the wrong pins but I'm pretty sure I did it right. Also included pictures.
