Monitors show no signal after purchasing new components. What to do?

I bought and installed a new processor (Ryzen 5 5600x), a new motherboard (MSI MPG b550 Gaming Plus), and two Corsair RAM sticks. Unfortunately, the monitors now display "no signal" after starting the PC and then turn off again. I've tried many things, like removing the BIOS battery and putting it back in after 15 minutes, or checking all the cables on the case and monitor, but nothing works.
Before the component replacement everything worked perfectly

My graphics card is the RTX 3050

Happy New Year and thank you in advance for your answers

You probably just swapped the CPUs a bit before you got the BIOS to a compatible version of the new CPU.

However, as your board allows you to update the BIOS without having a compatible CPU installed, you can easily recover it now.

Yes, you can. There is a USB port and a button on the back of the board. Then you press a USB stick with the matching BIOS file, press the button and then the BIOS is upgraded like ghost hand.

The first thing you want. Practically any USB stick is usable for this and you will already have any USB stick.
