My computer fails to boot


After the COMPAQ red and white splash screen, I am suddenly getting the message about \system32\DRIVERS\pci.sys is missing or corrupted, you may insert original Windows Installation disk [which I do not have because O/S was preinstalled] to try to repair the file  (or similar in plain white test on a black screen, after a row of tick marks which showed progress)


PC was booting successfully until a few days ago.


I booted to Mini XP from CD and found that C:\I386\system32\DRIVERS on the HDD was missing !!  I don't what other files are missing, but the i386 directory on the CD looks completely different to the one on the HD  ! (I did not expect them to be the same tho')


I do not  have an original XP Installation disk because the computer came with Windows XP pre-installed.

I do not wish to perform a system recovery to the original factory state because that would lose my legacy software, I think the term is.


What to do ?
