I have had the same problem with a few differences.
My computer is a Dell Vostro 400 desktop.
It became infected and I managed to remove the problem using Malware Bytes.
The system ran okay for a few days but seemed a bit laggy until finally right in the middle of viewing a webpage, the system shut down and would not reboot.
I have run the diagnostic and received the error message "Windows could not start because the followig file is missing or corrupt:
I am not really computer literate so I hesitate to use the reinstallation CD if it means loosing everything on my C drive.
Can you just confirm it is safe to use this disc or do I need to get a copy of the orignal XP disc which I do not have?
The reinstallation disc reads - Reinstallation CD Microsoft Windows XP Home Edition.
Thanks for any help.
