Issue with an AMD system

[moldogeo19]

Firts,thank you for your support.Recently,I wanted to upgrade my PC.I bought a MOBO(Gygabyte AX370M-Gaming 3) and a Ryzen 5 2600 processor.
When I installed the components in my computer,I tried to turn on it,and something was not matching.I thaught that my memory QLV is not available for the motherboard,then I changed the memory with another with available specifications.After that,the PC does not work.
I don't know what to do,I can't see the BIOS version,because I can't turn on the PC,I mean the components work,but is something that doesn't match.I have tried everything and now I started to think that is a factory problem.I phoned a guy and that guy says that the MOBO or the processor is deffect.I am sure that everything is connected well but I don't know what's the problem.
If you have a sollution,please tell me.Maybe it needs a BIOS update or I don't know.Please send me a message soon!But I cannot acces anything because if the memory(is compatible with the MOBO,but IDK why is not working)before to upgrade,I owned an i3 7100 processor and a MOBO.Idk what to do,a friend says that I need to return the products,but I don't know,maybe I've done something wrong.It doesn't post and I need a solution how to figure it out. Here's a clip with someone who has the same problem:https://youtu.be/auzjk8Ip8xs

Just needs a bios update, take it to your local pc store and they should do it for a small fee or contact AMD and they can loan you a bootkit to enable you to update your BIOS.

Also, do you have a graphics card installed, with the monitor connected tot the graphics card display outputs (not the motherboard display outputs)?

Yes,the GPU is connected where it should be.And now I know how the problem is called.It wouldn't post.It's a post problem.
Do you know how to solve it?

@racksmith101 already told you. You need to install a processor that's compatible with the older BIOS (an APU or first gen Ryzen CPU) and use that to update the BIOS. You can either take it to a local computer shop and see if they'll do it for you, request a BIOS upgrade kit from AMD, or just buy a cheap chip and do it yourself and then sell it.
