If you haven't already, please review the posting instructions here, and attach the requested log files. Without log files, our helpers will not be able to assist, and this will slow down fixing your machine.
If logs have been already been provided, our team of volunteers will analyse the provided log files to build a fix for your system. Please be aware that this may take several days from your initial post, due to the high volume of threads that we receive.
Step 1: WARNING! The following fix is specific to the user's system in this thread only. No one else should follow these instructions, as it could damage your system.
Download the attachment SFCFix.zip and save it on your desktop.
Save any work you have open, and close all programs.
Drag the SFCFix.zip file over the SFCFix.exe executable and release it.
SFCFix will launch, let it complete.
Once done, a file will appear on your desktop, called SFCFix.txt.
Open the file, then copy and paste its content in your next reply.
Step 2:
Restart the machine.
Run the command sfc /scannow in an elevated commandprompt and report the result.
If it fails, copy the file C:\Windows\Logs\CBS\cbs.log to your desktop.
Zip the copied file and attach the zipped cbs.log to your next reply.
