Just have the same problem.
I got new cpu, mobo and ram. After that i was having blue screens everyday, so I tried many things, including installing windows again. Nothing worked. The last thing I did was use amd cleanup tool, now I have this problem.
The app asked to enter safe mode, the screen became dark and it never came back from it.
Cannot use my other pc because I only get a dark screen, the fans were spinning, the mouse light was on, but that was it, no image, no sound apart from the fans, no motherboard logo too.
The other pc has a ryzen 4600g, a gigabyte b550m k, 2x16gb of kingston ram ddr4 2666Mhz. My psu now is a pretty cheap one, I had already paid for a new one before the problem happened, because a guy who understands better advised I should do it, but it has not arrived yet.
When it arrives I will take my pc to the guy to see if the knows something.
I am not a native speaker, so my english might not be perfect.
