Solid Green and white mobo lights on

I just finished building a PC but despite everything turning on (rgb and fans spinning) i get no post and both green and white mobo lights stay turned on. I have yet to update the BIOS but is that really all i need to do.

Specs:

CPU: Ryzen 9 5900x Motherboard: Asus ROG B550-F wifi Cooler: Arctic Liquid Freezer II 360 RAM: Crucial ballistix 32 (16x2) GPU: Nvidia Rtx 3080 FE PSU: Corsair RM850
