I’m building a new system right now, I decided to go with the ASUS ROG STRIX Z370-G Gaming WIFI (AC) motherboard.
CPU I7 8700K
EVGA 750 GQ 750W
Crucial Ballistix Sport LT Gray DDR4 2666MHz 2x8GB
Noctua NH-D15S cooler.
I mounted everything in the case but didn’t get a boot, so I started stripping the system down. The thing that happens when I turn on the power is that the colored led in the lower right corner of the board lights up in different color. But then nothing, when I press the start button ( or shortcut the start pins ). No fan spin up att all, no error message nothing. The PSU fan doesn’t even start.
I tried to remove everything including CPU to try to boot and at least get the status LED to show som error, but nothing. You don't solve problems by conecting your PSU to another computer. The problem is on your side, not another computer. So take another PSU and connect it to your board. That's how to eliminate what causes the problem.
I tried the PSU in another computer where it’s working fine, so I think I can rule that one out. I don’t have any friend or so with any computer gears so I can’t just easily swap things out.
Anyone with any suggestions? I’m suspecting that the motherboard is damaged in some way, would’nt I expect at least a POST test and fan spin up even without CPU, Memory etc? At the moment it's no difference if everything is installed or nothing on the motherboard anyway.
EDIT: Just tested the USB ports, I actually got power in them to.
