WORD CANNOT SWITCH TO GRAPHICS MODE.
 
Word cannot switch to graphics mode for one of
the following reasons:
■ You do not have a graphics card installed.
■ You do not have enough available memory. Choose
  File Close All to save all open documents,
  style sheets, or glossary files. Then switch to
  graphics mode.
■ You copied Word from another machine and the
  video driver is not valid for your machine. Run
  the Setup program again, choose to modify an
  existing version of Word, and choose to install
  a different video driver.
