Question New PC build not working ?

[_Mr_LyD_]

Hi everyone I recently made a new PC build, when I turn it on all the components start up but the monitor screen stays black, and a red LED on the top left of the motherboard lights up. Do you have any suggestions ?
My PC components:

• Case: NZXT H7 ELITE
• Motherboard: ASUS ROG Strix B-550 F Gaming WiFi II
• CPU: AMD Ryzen 7 5800X
• RAM: Corsair Vengeance RGB Pro DDR4 32GB (2×16) 3600Mhz
• GPU: Gigabyte RTX 3060 Aorus 12GB
• SSD: Samsung 980 pro 2TB
• Dissipator: NZXT Kraken X73 360mm
• PSU: ASUS ROG Strix 1000W

First things first, the B-550 chipset was released before the Ryzen 5000 series CPUs. Unless the motherboard was manufactured after the Ryzen 7 5800X was released (which it may very well could have been), it won't have the appropriate BIOS version. It may need a BIOS update, which will be difficult if not impossible without a compatible CPU.
