how to fix windows system32 config system error

How I can fix, change critical files Windows XP Pro?

Yesterday, my computer I found that all these tests performed, including a defragmentation of the system. The problem is the program froze in the middle of the fragmentation of system files and now when I start my operating system Home is on the computer, I get an error message before the login page may appear saying \ windows \ system32 \ config \ SYSTEM is missing or damaged. Is it possible that the files that I can solve this problem, and others who may have been injured, not to completely reinstall my operating system that all other programs and files are always in touch and connected with this operating system.
