I built this recently and my monitor won't post. The CPU Debug LED on the motherboard turned on then turned off after a few seconds. That is the only Debug LED that lights on.

Sounds like you need a bios update to support the 2nd-gen Ryzen CPU.

I asked the retailer that and he said it is updated ( though theres no sticker that says ryzen 2000 ready )! Why do I even bother asking them.

on most new mb there a small white bios label sticker on the bios chip to show the bios rev.
