[SOLVED] I installed a new cpu and now my monitor won't display

[VIGILantDoodle]

I recently got a new ryzen 5 3600 cpu and installed it into my Asus a320m-k motherboard but now my monitor won't detect my pc.
I don't think it's a problem with bios as I have seen many things say that the pc will at least display when the bios are incompatible.
What could the problem be?

I should add that all the lights inside my pc are on, my gpu is on and my mouse and keyboard is on.

That's not accurate. There's a reason that AMD has a whole program of loaner CPUs to update BIOS; if what you saw was true, there would be no need for that.

DID you update your BIOS? That's kind of the key question here you leave unanswered. You have to have BIOS 4801 or later.
