No video signal

   Hello Guys,

I just installed in my new configuration.
AB350 Pro4 BIOS 6.30
AMD RYSEN5 1600 (Summit Ridge)
HyperX HX430C15PB3K2/16 on A2/B2
Corsair MP510
But there is no video signal.
The AMD fan is running.
The power LEDs are on.
I tested with other memory modules, same problems.
I tested the cables, they work with another PC.
If the processor is not in place, the motherboard does not turn on.
Same problem with AB350 Pro4 BIOS 6.00.
Beeper is plug in = no beep.
I tried with a graphics card, no signal either (MSI Nvidia N720 1600 MHz PCI-Express 1024 MB).
The BIOS list say for version 6.00 or higher, "ASRock do NOT recommend updating this BIOS if ... Summit ... Ridge CPU is being used on your system.

Is there a method to downgrade the bios without a screen?

	Ryzen 1600 does not have integrated graphics, therefore you need a graphics card and connect cables (vga, hdmi, dvi or displayport) on the graphics card not on the motherboard ports. luck.
