When I'm done using the computer for the day I shut down the computer.
But the computer takes about 3 - 4 minutes to shut down.
When I try to boot up the computer it goes to a black screen and stays that way.
I then power off the computer using the power button.
After rebooting the computer it boots up normal.
It took me awhile to track this problem down because I could not figure out what was causing it.
Through trial and error the problem only occurred after using ccleaner.
I first downloaded ccleaner onto the computer on 1-22-20.
The current version of ccleaner I'm using is 5.68.7820 (64 bit) CCleaner Free
I'm running windows 10 Pro, version 1909 (64 bit)
I have updated ccleaner many times to newer versions with no change to the problem.
