I encounter this problem on a PC and on a laptop

[Murets]

I encounter this problem on a PC and on a laptop, both without SSDs, but with good specs in general (i7 8750h, 32GB RAM etc). I have a legit installation of W10 on both.

When I turn on the PC/laptop, I see a black screen for a long time (3-10 minutes, usually) before seeing the screen that requires my password (or pin or whatever). Sometimes, I see the mouse on the black screen, but that's all. Sometimes, the screen is completely black

Why is this happening? How can it be fixed besides going back to linux?

In ASTER you can send a technical report to technical support. Do this and describe your problem.

You should run a memory test using Windows Memory Diagnostic

In my opinion you are not right. Let's discuss it. Write to me in PM.

I am very grateful to you for the information. It very much was useful to me.
