Hi Jennifer

I commend you for asking the question - and for looking for a solution instead 
of just calling in a commercial repair technician.  The advantage of WAMUG is 
that OSX ignoramuses (like me) can ask for help on basic (or difficult) things 
but can still usually get helpful advice from members with their wide 
collective experience.

Good luck with your research.

Cheers
Alan
