Used a Vista Repair CD to attempt to repair the installation. This failed (could not detect a problem.
Tried a System Restore - there were none to restore to
Attempted to fix the MBR - no success
Ran all the Memory Tests and Utility checks provided with the PC - all showed passing
I ran Knoppix and was able to save off her documents and pictures. I don't know what else to do. I'm not sure if this is an OS problem or if somewhere they acquired a virus that shut the PC down. I am posting this under MALWARE, but if it should be in a different forum, please feel free to move it. I appreciate any and all help.
