Hi Eternal,
Going back to your orginal chkdsk scan that you ran earlier, it does have few issues and if you run the command below it will hopefully repair the damage.
Look in your start menu for 'Windows system'. (It's near the bottom)
Open the drop down menu and you should see 'command prompt', right click on the Command prompt icon in the start menu and you'll see two options.
One is to pin the app to the start menu whilst the other option say's 'More'.
You need to click on the 'More' option and another menu box will appear.
The menu box that opens gives you a further 3 options, all you need to do is click 'run as administrator'.
Type or copy and paste this command in the admin command prompt box:
chkdsk /r
Press enter and you will need to reboot as chkdsk scans outside of windows
This will look for broken sectors on the drive and if possible repair them.
