Hello,
I just installed an MSI X570S EDGE MAXI WIFI motherboard. I'm having a problem when starting the computer. Most of the time, there is no display on the screen. After powering on, the screen remains in sleep mode. All components seem to be functioning. Unfortunately, it happens rarely that the display works and I get to the W11 desktop. Applications work normally. If I shut down or restart the PC, the screen stays in sleep mode. I have to restart several times before getting a display. I've checked the various connections on the motherboard. I think that if there were any wrong connections, it wouldn't work at all. Normally, the screen is connected via D.P. I did a test with HDMI with the same issue. I tested with a second screen that only works via HDMI, with no results. On the motherboard's Dbug LEDs, the indicators light up and go out one after the other: CPU (in red), DRAM, VGA, and BOOT. The VGA indicator stays lit longer than the others, about fifteen seconds. The problem is, I don't know how to interpret these LEDs. When the screen is in sleep mode and I unplug the D.P or HDMI cable from the graphics card and plug it back in, the screen comes out of sleep mode for a minute and in most cases goes back to sleep mode. I took advantage of the rare times when I had a display to update the motherboard drivers from the USB stick provided with the card. Another important piece of information: I can't access the BIOS (via the 'DEL' key) or access BOOT (F11 key). During power-on or restart, if I press the 'DEL' key several times, I keep ending up on the W11 desktop.
'I'm losing it!!!!!!!

Here is my configuration:
Samsung C32F391FWU screen
MSI X570S EDGE MAXI WIFI motherboard
RYZEN 5 3600 CPU
AMD SAPPHIRE R9 290X TRI-X OC graphics card
Power supply: ANTEC HCG650 GOLD
16 GB of RAM: DDR4 3200 MHz
1 M.2 SSD for the system

Thank you in advance for your help.

Hello,
Fed up with searching for the origin of the problem, I disassembled the motherboard and reinstalled the old one, and now there are no more issues. So it’s going back to the sender.
