Context: This PC (not mine) is a desktop Ryzen system with the integrated graphics card (G series chip), 16GB of RAM and 2 drives: an SSD and a hard drive. Windows 10 is installed. It was working normally before
Problem: when the PC posts (fan spinning and everything), after the initial AsRock motherboard message is displayed, there is nothing, total black screen, and after a while the monitor shuts down because it has no input. I tried getting into the boot menu and selecting to boot from Windows Boot Manager. The Windows logo briefly appeared, but then it was total black again. :(
I think it has something to do with boot / OS problems ....
