Windows 10: PC suddenly slow, not saving events in log & will "forget" to boot any way but normally.

Hi all,I have an issue with my main home PC running Windows 10 Pro which has me almost banging my head against a wall. Hoping someone can help.Last week I got a BSOD. I Was running X-Plane 11 which is pretty processor intensive, so didn't think it too serious. However when restarting, it was extremely slow. But, it's the attempts to diagnose & fix which are bringing up some weird & annoying symptoms.The PC has been restarted many times in the last week as I try to diagnose & fix the issue. However, every time I look in the event log, it's as if the current session is the first one

:)

 

slow log in

I meant log in time not boot up time.... boot up is already fast but when log in by entering the password, very slow to see the desktop screen.
