SFC indicates corrupt files & was unable to repair them

[Bakerman]

Windows 7 64 bit home built PC ...I used system file checker ( SFC)

Used CMD as the administrator ran scannow [ C:\Windows\system32> sfc scannow] & message indicates corrupt files & was unable to repair them. Was not able to read /interpret CBS.Log file in C;\Windows\Logs\Cbs\Cbs.log

I have my original Windows disks

Perhaps someone can advise as to how I can replace corrupted files with a known good copy manually ???

I have backed up my drive in 2 areas using Macrium Reflect.
