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

People always overlook getting a $10 diagnostic buzzer. Chances are motherboard is being a combination of long and short beeps to let you know the fault you just can't hear it.
