You did a lot of things. Lets do the basic
Open a CMD window and type
chkdsk c: /f
It will say the disk is in use and if you want to schedule to next start = yes
Reboot.
Pay attention on the results, specially bad blocks or bad clusters. Report.
Back to windows, open a CMD window and type
sfc /scannow
If it find issues, reboot and repeat 2 more times.
