When I turn on the power, all the fans start spinning, but no BIOS beeps or video output. When i press keyboard buttons nothing happens. Does this mean that the motherboard is functioning? Is there a way to test if the CPU is an issue that doesn't involve me buying a new CPU? I have tried with and without the GPU (MSI Twin Frozr III GTX 660), with no difference. I have a speaker plugged in for testing purposes.

EDIT: Bios sticker on board says P3.50, which is supposed to work with Ryzen 3000.

Update: So, I now get monitor backlight and keyboard numlock light with the Ryzen 3 2200G, but still no post. I am getting the same on 2x ASUS PRIME X470 boards with both a Ryzen 5 3600 AND the aforementioned Ryzen 3.

Update 2: One of my ASUS PRIME X470 boards worked with the Ryzen 3 2200G - Bios Update - Ryzen 5 3600, and is now installing Windows 10 Pro. So that is progress at least.

All suggestions are much appreciated - thank you
