My Win 10 pc started having this mysterious problem about a month ago. Directly after the very first image I see on turning the pc on (that image is my hp omen logo with windows circling dots animated below) the screen goes black (monitor on but displaying just black) for a very long time, 10-20 minutes. There is no obvious activity, no hard drive sounds, fans sound normal, like it's literally just counting down a timer.
Then it just comes on and acts completely normal until I turn it off again.
I haven't found anything obvious in the event logs and I'm not sure where else to look. I have reinstalled windows thrice in the last month. I hadn't realized that the problem was a hang and not a complete failure so I reinstalled. The problem takes a bit to return when I do that, about a week.
I suspected Windows updates so I froze those, I think I have ruled them out though I did allow some updates (Like Xbox app and services) through recently, and the issue subsequently returned. I saw a lot of Oculus related spam in the event logs and uninstalled it but the problem remains.
I'm not too sure where to go from here. No scans are finding bad hard disk sectors either. Thoughts?
