I am in desperate need of help.  I am a college student and depend on my computer very much.  The main problem I seem to be having is in Microsoft Word.  When I try to complete a complex function, I get an error message say that "there is not enough memory...to complete this operation" but I have no clue how to fix this problem!

my computer is also very slow so I think something might be taking up my ram.  Please help me fix this problem ASAP, without Word I'm swimming up the a river.

thanks for your help,

Nik
