Diagnostics Test
System File Check
Please try following:
Open an admin command prompt
Copy/paste "sfc/scannow" (without quotes) and press enter
When it finished reboot your system
Open again an admin command prompt
Enter sfc/scannow again
If sfc/scannow says "Windows Resource Protection found corrupt files but was unable to fix some of them" after the second SFC, please upload the cbs.log file located at {windows partition}\Windows\Logs\CBS\, if the file is too large try a 3rd party uploader like dropbox, onedrive, google drive, mediafire etc.
System File Check(SFC a.k.a. Windows Resource Protection) needs to have your system rebooted in order for sfc to try to fix the problems that it finds.
