red led My brand new pc is not booting

[ARCHA1C]

Today i built my first pc, and It is not booting.
Specs: 
ryzen 5 3600
B450 aorus pro
16 GB g skill ripjaws 3000 mhz
650w psu
Cooler master 212 black
Rx 480 gigabyte

Basically, the gpu is not being powered, its completely shut down, there's a red led in "dram" and it goes to cpu sometimes for like 0.5 seconds. I have plugged and unplugged the cables several times, tried all the RAM slots, removed the CMOS battery many times, reinstalled the CPU, i tried plugging another graphics card and It didnt work either, in both pcie ports, i unplugged and plugged the modular cables from the psu, the m.2 SSD also has a red led, and i've also tried replugging that in, and i think that's all i've tried.
I've also paid 15 euros for a bios update. I guess the motherboard is causing the problem, but i really don't want to send it back, i just want it to work if you have ANY suggestions i could try, please tell me, thanks in advance.

I don't think the updated the BIOS all the way to ryzen 3000 compatibility the reason I think that is because I built a PC with the same MOBO and when we tried to start it up with out the BIOS update it exhibited similar problems but after the BIOS update it worked perfectly fine. you could try going to a store with a relaxed return policy(Best buy worked for us) and buy a ryzen 2000 processor and use it to try to update if it doesn't work with that chip then its a RAM or mobo problem. to narrow down beyond here i would try putting only a single stick of RAM in and trying all of the slots with both of the ram sticks and if it doesn't work then then most likely its a MOBO problem

Did you give whoever did the update your new CPU to make sure the update was completed successfully? If not, bring it back in to make sure.

have you tried fresh installing your OS?

It does not POST, so you cant install an OS.

 

BIOS does not support the CPU.

That's what I get for not carefully reading op.

Yeah, i was also suspecting that the store that i paid to update the BIOS didnt do it properly, i'll RMA It and see if they do it right this time
