Hi,
That appears to be a problem with your hard disk.
Do the following:
1. Click Start

2. In the search box, type
cmd
3. In the list that appears, right-click on cmd.exe and choose
Run as administrator
4. In the command window that opens, type
chkdsk /R and hit enter.
You will be prompted whether you wish to schedule and disk check at next startup, choose YES, then reboot your PC. Make a note of the chkdsk that occurs at boot and post the details back here.
Install and run
CrystalDiskInfo - take a screencapture image of what the program reports for your C: and post it here.
Regards,
Golden
