hi @Hexagon37 ,
The only thing left is to check and repair the disk structure
Right-Click Windows Command Shell Select Run as Administrator
c:\> ChkDsk /f/r C:
Message asks if check disk on next restart type Y
Restart PC
The disk check will start in about 20 minutes and will probably pass error-free, then restart Windows.
Finally, there was a problem with certain graphics cards after an update and this thread solved the problem
That nothing else can think of will fix this.
