Perhaps you should try the clean install again or a repair install, or even an offboot sfc /scannow, but let's see what sfc couldn't repair.
Open a cmd prompt as an admin and enter -
findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >"%userprofile%\Desktop\sfcdetails.txt
This will put an icon onto the Desktop which will open the CBS log in Notepad which you can then copy & paste into the reply box.
