[SOLVED] Asrock AB350 Pro4 with Ryzen 7 2700X doesn't boot

[spike6]

I have wierd problem. I tried this MB with older CPU AMD A6 so I know MB is working. I thought I must do the BIOS update so I did from 4.50 to 4.70 which is version that Ryzen 7 2700X need. But still didnt work with that so I updated to 5.40 but still same problem. PC startup but nothing on the screen. I tried DVI, VGA even HDMI integrated on this MB. I also tried GPU but still nothing. I changed memory even tried with empty slots. Nothing so I sent CPU back to seller and he gave me back money. I bought another Ryzen 7 2700X from other seller but still same problem. ANybody knows?

You have to use a graphics card with that CPU and connect the monitor to it, not to the motherboard.
