Solve : Fatal Error Causing Inability to Start PC?

1.	Solve : Fatal Error Causing Inability to Start PC?
Answer» I have a relative who has encountered a BLUE screen fatal error occurrence at OE-015F:00000013 in Windows 98. A missing file SYMTDI.VXD is mentioned and I believe this to be a NORTON Symantic file. My plan has been to either delete the Norton programme, since she now uses ANOTHER anti-virus programme, or at least remove reference to this file from within the registry. My problem is that I cannot start the PC without the fatal error message APPEARING. I cannot get into Safe Mode without the message appearing. I've tried starting from a Windows 98 startup floppy using various commands at the A:\ prompt. I've tried starting in MS-DOS using various commands at the C:\ prompt. I did manage to restore a previously successful registry with scanreg /RESTORE, but that hasn't helped to start the PC. Short of reinstalling the operating system, I am running out of ideas and would very much appreciate some HELP/ guidance.
