Hi Mellisa, Before we go adding more Physical memory, Lets try setting the Virtual Memory to System managed size.
Heres how, Click start -Right click my computer -
Properties - Advanced system Settings - Under Performance, click on
settings - then click on the
advanced tab - Under virtual memory click
change,
If like mine, you have 2 drives, Untick the box at the top that says "Automatically manage paging file size for all drives"
Now make sure theres a tick box in " system managed size " then press SET. followed by OK.
Reboot, and try Word.
