Ok according to this we need to narrow down the content of the log file. Browse to command prompt (start menu>all programs>accessories). Right click and select run as administrator giving it permission if prompted. Copy/paste the following line in the box and hit enter [right click on the window and select paste to paste]. Code:
findstr /c:"[SR]" %windir%\logs\cbs\cbs.log >sfcdetails.txt
Post back the newly created sfcdetails.ext file. For me it put the file in the folder listed in the command prompt. You might want to change that to a better location. I would type in cd c:/ to put it in the root of your c drive.
