Go into your system information or even log.. look in Office applications, or something like that, and look for what dll is crashing it. My dad had a conlict with this in office as well. Sometimes, its as simple as an evil print driver.
Then, when you find what crashed it, go on a search on what the file is.
Better yet, send a picture of what the diagnostics in System information shows.
