In addition to your topic title
reinstalling windows gone really really really wrong
So, you have me a bit confused with this:
no i want to repair it ?
i want to keep all my files
A clean install will make your programs and data unavailable (unless your data is on a second partition, then your chances of keeping it are 50-50) Your programs will need to be reinstalled after a clean install of XP.
A repair may not be possible or practical for you:
what i had to reinstall windows because it kept on prompting messages that i was missing window files, i had many virus and my net was no longer working.
You need to be more specific as to what exactly you want us to help with. Usually a System File Check is performed before a repair install, and if a repair install fails, then a clean install is probably necessary. Where and how do you have your data backed up at?
