WINWORD caused invalid page fault

One of my is experiencing a Winword error without getting into word. The error is:
“WINWORD caused an invalid page fault in module KERNEL32.DLL at 0247:bff9db61”. She gets this error when going into any of the Office 2000 products and sometimes programs that are not even related to Microsoft. She had Office97 SR2, so I upgraded Office 2000, thinking this would help…It didn’t. Does anyone have any suggestions?
