Hi, I had same problem in the past. I tend to login in the local admin account and for some reason that's not having any black screen issue but when I log on to the affected user account its having a black screen issue.
I'll go back to local admin login and check if all the update and drivers are up to date and if that didn't fix the issue I roll back the latest update.
If that didn't work. I use this command 'sfc /scannow' to find that corrupted file.
Half the time that won't work either
My last resort, I will restart the machine. Sometimes that won't be enough and I have to physically unplug the desktop's power cord, to have it boot again.
The issue tends to surface every time there's an update release. This is a nooby question: Is this a normal thing after an update?
