No post-no display

I have a ryzen 1200 and brand new ryzen 2700x on a msi x370 gaming plus board. I replaced the 1200 with the 2700x and the board is now saying bad cpu and bad ram. So I swapped them back and now the board saying the same for the cpu that was working earlier.

Reset the BIOS and if you want that 2700x working, update the BIOS. It's likely the current one is an old one and has no clue wtf a 2700x is so it panicks. A BIOS update solves this.

 

edit: update the BIOS while the 1200 is installed.

How would I go about resetting the bios? I tried clearing the cmos and no matter what I cant get any display. Ive read that a new cpu could take a while to boot for the first time and thinking maybe that might be it.

If you didn't update the BIOS prior to putting in the new CPU, that board would not recognize that CPU. It needs the BIOS update to be compatible with newer Ryzen chips. See if your board has the USB BIOS flashback feature, as that will allow you to update the BIOS with no CPU.
