New build won't boot, no beeps

[AndreaNocche]

Hi.
I've built a new PC with these components:
- AMD Ryzen 7 2700X CPU
- CoolerMaster V8 CPU fan
- Double HyperX HX432VC16PB3K2/16 RAM (16Gb)
- Gigabyte AB350-Gaming MoBo
- Msi GTX 960 Gaming 4G Graphic card
- 250Gb Samsung SSD
- 3Tb Seagate HDD
- Corsair CX550M PSU
I attached a beep speaker too.

When I boot the machine it starts speeding the fans, after 1-2 seconds the GPU stops and the fans slow down, the screen does not light up, no beeps, no life.
I tried to remove all the components, remaining only with CPU, PSU and RAM, even without chassis.
When I remove the RAM the fans start slowly, and trying with the GPU it continues "running", but still no display and no beep.
I tried to replace the PSU and replace the battery too, same story.
I dont't know if this MoBo has LEDs for errors, but only the side LEDs (the ones that light the line on the board) light up.
Any ideas? Thanks.

it could be that the cpu is not supported by the BIOS,
test the mobo with 1st Gen Ryzen (friends or local repair shop (if they have one)) or get a X470 board

@gigantusmagnus Tomorrow I'll try to the repair shop, my friends have all Intel or AM3+ sockets.
If the problem is the CPU not supported, can a BIOS update solve the thing? Maybe at the repair shop they can do that.

Solved by updating the Bios via an older CPU, the Bios was f6 version and the Ryzen required f22.
Thanks!
