  • The scannow indicates operating system corruption.

    It was not repairable using scannow.

    If you want more information about the corruption that was not repairable you can view the cbs log:  C:\Windows\Logs\CBS\CBS.log

    Are your files backed up?

    Have you made an image of your drive?

    If you have an image or your files backed up you can perform a clean installation or reset and remove everything.

    If your files are not backed up and you do not have an image there are other options.

    Another alternative is using the windows recovery or windows advanced troubleshooting menu and finding a valid restore point.

    If there is no restore point you could perform a reset with save files but you would lose applications.

    Consider performing an upgrade repair installation.

    You will need your product key.

    If you don't have it handy you can get it using command prompt.

    To perform an upgrade repair you will need either a second drive either HD or flash drive in which you can install a windows 7 iso.

    To download a windows 7 iso:  https://www.microsoft.com/en-us/software-download/windows7

    You will need to boot your computer, open file explorer, then this pc, then find the iso on the HD or flash drive.

    Then you will click on setup or setup.exe which will launch the iso.

    The product key will need to be entered.

    When it launches you will see install in the center and you do not want to click on it.

    Instead look to the lower left to perform the repair installation.

    There is another alternative in case you prefer windows 10 instead of windows 7.  

    It may still be possible for a free upgrade to windows 10.

  • Hi,

    As some parts of your logs is garbled, I just checked the remaining identifiable log.

    Those are the corrupted files I found:

    Try to replace those files by coping from a same Windows 7 version device. Then check the issue again.

    Route of those files:

    C:\Windows\System32\SCardSvr.dll

    C:\Windows\Microsoft.NET\Framework64\v2.0.50727\cscomp.dll

    C:\Windows\SysWOW64\migwiz\dlmanifests\ADFS-WebAgentClaims-DL.man

    If the issue persists after replace them, you need to perform an In place upgrade to fix the issue.

    Bests,

    Joy.

  • Hi,

    Thank you for you update.

    Reinstall action always useful for corrupted system files. It seems like it is also useful for you.

  • You very likely have a bad hard drive which is what caused the system file corruption and which is also causing your system to run so slow.  You need to backup what you can, buy a new hard drive, re-install the OS and copy your personal files back to the new hard drive.

    Thank you. I changed SATA cable and reinstall my Windows OS and everything is OK.
