Question New mobo startup issue

[Nomapita]

I've just finished to install my motherboard (Rog b550f) and plug my pc. At first everything worked I got into the bios and udpate everything. But when I reset the pc, the fan and peripheral turn on but nothing is shown on the screen. I've tried to change ram and reset the bios but the same thing happen. It work once but after a reset nothing happen.
