Tips for Windows XP
Step 1:
Boot up your Computer with your Windows XP Installation CD before the Windows XP Logo boot screen appears press R (Repair) on the black screen that comes before the boot screen, repair your hard drive. If you cannot do that, install a NEW windows version (XP, Vista, XP PRO etc etc..) then once logged on, go to Start > My Computer > Local Disk © > open up System32 (System Folder) try locating the missing file that keeps giving an error (if it does). If it is there but corrupted go to Start > Run type in the search box 'chkdsk' (normally located in 'C:\WINDOWS\system32'). Run the Disk Check to find any corrupted files in your system, then repair them.
I think thats it lol.
