    i would suggest 2 things to start...

    type this: sfc /scannow (this will check the file system, if errors are found will replace with original, most likely will require xp cd)

    if the above does not help try Registry Mechanic


    PS: have you tried running the system in "diagnostic startup" ... start>run>msconfig
