B350m pro-vdh ryzen 3 won't post

Hi, I made ryzen system and everything seems okay but it won't output any video, i have an rx 580 and made sure everything is were it's supposed to be connected. In the ez bios debug I got ram and cpu lights and stayed on. I changed the ram dimms from 2 to 3 and now i only got the cpu. I unstilled the heatshink taked out the cpu and made sure there wasn't any bend pins, reinstalled it and still got that one light. I unplugged the power to the cpu and plugged again and still same result. I though about reseting the bios but i don't know exactly how to use the jumper but tried with a screw when it was turned off. Nothing happened. I heard somewhere that i need an updated bios to use ryzen 3? Or maybe the mobo or cpu is damaged? I don't exactly know how does ez debug leds work but most say that the ones that stay on are the faulty, some say that all must be on? Sorry for long threat im desesperate on what i should do.

    Unfortunately you need a cpu that is supported by the BIOS version that is installed now. Then you upgrade to the latest BIOS for Ryzen 3 support. Maybe the retailer where you purchased the motherboard can help, or maybe you know someone who can loan you an older Ryzen cpu.

    You'd need a supported CPU. A local pc shop might help. Or, you can RMA the board and ask for a BIOS update.

  10. Best advice I can give you is switching the cable connecting your PC to your monitor because that was my problem when I couldn't post. Try different cable types because sometimes the cable you have might not be supported by the drivers on your GPU. If you want to test if something is broken, run the system without the part you think is broken and if it beeps the part works properly. Before you go crazy and replace anything like I did, test different cables.
