Motherbaord won't start.

I recently bought a X470 Taichi Ultimate motherboard and I got it installed today, I plugged in the power cable to the PSU and the LED lights came on and then faded in and out but on pressing the power button on the tower nothing happened, so I tried the power button on the motherboard itself and same thing happened. I tried anything and everything I could find online about it but I kept getting the same result, nothing. No sound or movement at all. All the cables and wires where all in the correct places and the RAM stick was properly seated in its slot. I can't for the life of me figure out whats going on here.

Second the cpu and ram. If it's a 3000 series processor and your board is on a old bios that isn't 3000 series ready. It needs to be updated first.

The bios is P1.50 which is what came with the board. But the problem I have is it won't start up at all. It's kinda hard to update the bios when the board isn't on.

I tried testing the motherboard outside the case with just the 8-pin 12V and the 24-pin as suggested by ASRock tech support and I got the same result as before. The lights came on and nothing else happened. I got a feeling that this motherboard was either DOA or something else happened. The board is getting power because if it wasn't the lights wouldn't come on but it just won't turn on.

Some retail outlets will occasionally test boards before shipping them out and if their tech left the jumper in the clear position it would result in exactly the behavior you describe. Even if you have moved the jumper yourself (to clear CMOS) you may have been moving it from clear to normal and back to clear again.

I can't locate the clear CMOS jumper anywhere on this motherboard. There are two clear CMOS buttons, the first is next to where you would plug the power switch, reset switch, HD led and the P led and the second is located in the I/O panel at the back. Even according the manual there is no other clear CMOS other then the buttons.
