windows could not start because the following file is missing or corrupt

[NIcaBoy]

I am getting an error message that says "windows could not start because the following file is missing or corrupt \WINDOW\system32\config\SYSTEM." I have tried following all the articles on microsoft but none works for it. I didnt have this problem for so many years now but all of a sudden it started. Can anyone please help me out? Thanks

If you have lost the files suddenly then it could be a problem of hard drive failing. Check the make and model of the hard drive and then download its diagnostics utility from the manufacturers website. After that this utility will check the health of the drive. Usually the downloadble file will allow you to create a bootable floppy or CD. Incase the drive is failing then you must replace it and copy all the important files you want to keep from the old drive as soon as possible and then do a repair install.
