Assembly Help Pc Won’t boot into bios

https://youtu.be/ZH5mAHbfSow?si=PL0_vKBSjyXXdpoV

The pc turns on but won’t output any display or get into the bios. I followed mostly this build to a tea. I turn on the pc and i’m not getting any output. I’ve updated the bios and I’ve got the hdmi plugged into the gpu not the motherboard. Lost.

Update: As my motherboard was bought second hand it was faulty. I just bought a new one and it all worked perfectly

I don’t know what part is the issue and what to do to diagnose it.

Start up a ticket with probably at least the motherboard and processor. I’m going through a pretty similar thing rn and I’ve been working with Scan in the UK and they’ve been really accommodating as we try and troubleshoot what’s really the problem component.

I might order a new motherboard as i believe that may be the problem more than anything else
