Geschiedenis van "Why does the screen boot so slow"

So today when I boot up the laptop, it went into the login screen, and I got in. Once I got in it's a black screen. I press ctrl+alt+delete to get into task manager. I'm still able to run my games on steam. And after like 5 minutes the screen comes up. So I want to ask why does it take so long to load to the screen
