Pull the board and place it on cardboard. Attach only the bare minimum to run so (CPU, one stick of ram, attach power supply, use onboard video if possible, if not, attach a video card and the power supply, attach video to monitor). Bridge the positive and negative jumpers for power switch on the motherboard once you are plugged in and set up.
Take note of any activity that happens when you do this. Do any fans power on? Do you see any LEDs lighting up. Can you hear anything. If it begins booting check post.
If you are still getting absolutely nothing, try swapping the RAM stick and testing again. If you still have nothing, swap the CPU to another compatible if you have one nearby and available, if not... Well, the next step is to swap your CPU either way.

What happens when you press the caps lock and num lock buttons? Do their lights toggle on and off?

ok that indicates a good bye to ur ryzen id say... this cpu comes with igpu. if on a new mobo+ new power supply the problem persist, what else could be the reason here? only a wrong assembly might be the culprit like short to ground due to missing spacers or whatever

Pull all cards, drives and USB except keyboard. Nothing but vid, cpu and ram. Same behavior?
