My first build no POST

[Seif45]

I just finished my first build, made sure everything is connected and when I powered on, everything inside the case seems working all the fans are spinning and lit up with rgb, the GPU fans are spinning and lit up, the aio fans are spinning and the pump is lit up, the chipset light is lit up as well but nothing is displayed on the screen and the keyboard and mouse are not lit up.
My specs are:

case Corsair 4000x
motherboard asus prime x570-p
CPU amd ryzen 9 5900x
GPU Asus Tuf gaming 3070

ssd 970 evo plus 2tb

rams 2x8 gb G.Skill ripjaws v
ANY SUGGESTIONS?
