Hello, I have just finished my PC build but my pc just won't boot. There is a yellow LED shining on the motherboard all the time. Also, when I boot the PC the CPU fan spins up for some time and then suddenly stops.

Components:
  • Asus ROG strix B450f-gaming
  • 3060TI
  • Amd ryzen 7 3700x
  • Samsung 256 M.2 nvme ssd
  • 600w be quiet PSU
  • 2x4GB DDR4 Ram
There are no USB devices connected, just the monitor.

Any help is greatly appreciated.

So the bios update didn't help. But I can tell my monitor recognizes something as it goes from "Check your wire" to "no signal" whenever I try to boot the pc.
