First run CHKDSK and SFC - (again??)
Please run a full CHKDSK and SFC scan....
type in the Search box
CMD.EXE
right-click on the only file that is found
Select Run as Administrator
- the Elevated Command Prompt window should pop up
At the Command prompt, type
CHKDSK C: /R
and hit the Enter key.
You will be told that the drive is locked,
and the CHKDSK will run at he next boot - hit the Y key, and then reboot.
The chkdsk will take a few hours depending on the size
of the drive, so be patient!
After the CHKDSK has run, Windows should boot normally
(possibly after a second auto-reboot) - then run the SFC
SFC -System File Checker - Instructions
Click on the Start button
type in the Search box
CMD.EXE
right-click on the only file that is found
Select Run as Administrator - the Elevated Command Prompt window should pop up
At the Command prompt, type
SFC /SCANNOW
and hit the Enter key
Wait for the scan to finish - make a note of any error messages - and then reboot.
Try running the CheckSUR tool -
System Update Readiness Tool that fixes Windows Update problems is available for Windows 7, Windows Vista, Windows Server 2008 R2, and Windows Server 2008
assuming it 'installs' OK - or even if not - post the CheckSUR.log and CheckSUR.persist.log files and someone will take a look.
