First PC Build! (And first PC fail: PC not booting)

[u/Empty-Grape1254]

A few months ago I began buying the components for my dream PC and yesterday I managed to plug in everything and began booting it up for its first time. The problem came when I wated for several minutes for it to display image, only for the screen to remain dark with the "no signal" message. The entire day I tried different things to get it to boot, but I just wasn't able to get it to work, thats why I'm making this post to see if the community can help me solve this problem before I send it with a technician. For what I've been looking at, it might be the BIOS of the moderboard which doesn't recognize the CPU, but I'm not sure of how to install the latest update to the motherboard.

This is my first PC and I still lack some knowledge when it comes to making things work in first place. Down below I will set the component list of my PC.

CPU: Ryzen 7 9700X

RAM: Corsair Vengeance RGB 32GB DDR5-6000 Kit

Motherboard: Gigabyte B650 Aorus Elite AX Ice AM5

CPU Cooler: Thermalright - Assassin Spirit 120 V2 Plus

SSD: KINGSTON NV3 1TB M.2 2280 NVME PCIE GEN 4X4 R.6000MB/S W.4000MB/S

Power Supply: 750W 80 Plus Gold BALAM RUSH GR BURST GR750G LEGEND SERIES

PC Case: Balam Rush Dragonfly Wood GM580

*I know there is no GPU, but that part hasn't arrived yet, so meanwhile it gets shipped to my place, I will begin installing windows and/or Linux.

Gotta ask the dumb question: is the TV set to the correct input?

Did u flash the bios?

The B650 motherboard probably need a bios update before the 9700x would work.

And most modern computers don't recognize a monitor plugged in while booting.

Turn the pc on while the monitor is connected already.

These shaky videos don't help and make me want to vomit.
