Well I have a Mobo ASRock b450 fatal1ty itx with ryzen 7 1700x o installed a HP EX900 I installed Windows and everything was normal if I reset the computer
Everything works ok but if I turn off the PC it automatically doesn't recognizes the m.2 anymore in the bios
So I noticed that the solución for now has been unplugged the power and plug it in again and the computer will start boot again
But that's obviously not a real fix I never came across with this so I'd love to hear opinions I don't really know what happens when you take the electrical power down and on right away but is doing something ...
