Manu thanks, I tried with a graphic card and the PC is working perfectly]]> Tue, 07 Jan 2020 00:33:44 +0000 https://forum.asrock.com/forum_posts.asp?TID=13346&PID=71817&title=mobo-b450m-pro4f-doesnt-boot-screen-off#71817 <![CDATA[Mobo B450M Pro4-f doesn't boot screen off : There is no GPU integrated on...]]> https://forum.asrock.com/forum_posts.asp?TID=13346&PID=71776&title=mobo-b450m-pro4f-doesnt-boot-screen-off#71776 Author: jdillipl

There is no GPU integrated on the motherboard. There is integrated graphics in a Ryzen series APU. The Ryzen 7 2700 is not an APU. Looking at page 6 of the Quick Installation Guide:

Integrated AMD RadeonTM Vega Series Graphics in Ryzen
Series APU*

Do you happen to have a spare video card for testing?

I finished assembling a new PC. I'm not new in such matter. I followed the ASrock manual procedures and when I switched on the pc the mouse, keyboard, ssd, DVD, start working but the screen remained dark and "no signal" appeared. It was impossible to enter in the BIOS. After few second 5 beeps came out. The viedeo was switched on and setteted to HDMI input and tested on other computer it works pretty well.
I tried to unplug all the peripherial but the results were always the same.

The PC configuration is the following.
MOBO ASrock B450M Pro4-f
CPU Ryzen 2700
RAM 4 Corsair Vengeance LPX DDR4 CMK16GX4M2B3200C16R
SSD SATA III 960 GB
GPU Integrated (no esternal GPU installed)

Could you help me to understand wath's wrong?]]> Sat, 04 Jan 2020 04:39:52 +0000 https://forum.asrock.com/forum_posts.asp?TID=13346&PID=71759&title=mobo-b450m-pro4f-doesnt-boot-screen-off#71759
