New PC build - Black screen

[ganons]

Hi

I built a PC last night and I get black screen only, doesnt show bios or option to go into it. Everything powers up even the keyboard.
I have:
i5 6400 CPU
2x8GB DDR4 Ram
Asus H110i-Plus motherboard https://www.asus.com/Motherboards/H110I-PLUS/ (new from Amazon)
650w Fractal PSU
1TB HDD without OS
Zotack 1060 GPU

I reseated the CPU and Ram and tried 1 Ram stick on both slots. Tried the HDMI on the board and GPU, also tried without GPU. I know the components work as I had to return an MATX board and that went into BIOS and an older HDD with OS)

So what can I do?

Sounds like you've done everything you can. My guess is you got a bum motherboard.

That is the number one suspect.

Presuming you also booted bare bones out of the case, tried a different HDMI cable, and confirmed the monitor works. PSU being faulty is another possibility, but very unlikely given the info you provided.

If its a faulty motherboard, it shouldn't switch on at all should it?

Just to clarify, without having an OS, it should still show something on the display right? Like press f2 for bios?

I have worked on many bad boards that would power up, fans spin, etc. but that is it.

Fixed! It was a bent pin in the bottom left corner.
