I'm building a computer for my friend.
We finished building it and tried to start it, but my natural enemy when it comes to building computers, the power button, doesn't work.
in the Manual on site 12 (1-4) we can see an info graphic how to connect the power switch, power led, reset switch, hdd led etc.
I actually connected them exactly like they say in the manual, but it won't work. nothing happens when I try to push the button. The mainboard certainly has got power because when I plug in the ethernet cable, the LED start to glow, which is an indication that the mainboard has power.
I also tried to "turn around" the power switch so the text on the cable faces the bottom instead of the top, and also i tried both position for the 2 one-pin power-led cables.
I made pictures of my setup but they're so low quality, It wouldn't help at all. sorry for that.
I know that there is probably not a straight forward solution to my problem, so what steps can I take to find out what causes the problem? thanks a lot!
EDIT/UPDATE: Hi guys, thanks for all your suggestions. The faulty part was the processor. It was the first time I installed an AMD processor instead of Intel. Intel processors have this kind of "cap" you put on top and close after installing the processor. AMD don't have that, you have to push them in by your own. looks like I didn't push enough the first time and the pins weren't correctly seated.
I'm gonna accept the answer that says that you need to check every component, because that's what saved me. If it doesn't work, start again from 0.
