I don't know what to tell you. From my standpoint, everything is clean corruption wise and the computer is ready to be used. If you are unhappy with the performance, you can either test the HW to see if that is the issue or format the drive and install Win7 again, but I do not believe Win10 is the culprit here as I've been using it since 2015.
You can even start a thread in another forum here at Sysnative to be assisted by someone who does HW troubleshooting more than I do, so they may be more helpful.
