Don't upgrade again yet, first we need to make sure there are no problems regarding corruption of files, drivers or hardware problems.
Please open admin command prompt (right click windows logo > command prompt (admin)), copy/paste command "sfc /scannow" (without quotes).
We want sfc to say "Windows Resource Protection did not find any integrity violations".
If sfc doesn't say this when finished you need to reboot for sfc to fix the problems, after you rebooted try sfc /scannow again.
Keep doing sfc /scannow command, reboot, sfc /scannow a few times.
