Technical difficulty

I have had my trusty old powerbook from 2003 to 2008. It served Martha and I very well. All the way through graphic design school, internships, multiple wedding announcements, ward directories, freelance projects, creating resumes for professional jobs...etc. It has even seen embarrassing times when I made a BYU Graphic Design slide show for our graduating Christmas Party and the iDVD zoom setting narrowed in on my professor Adrian's crotch. Yeah if you knew Adrian it would be 1000 times more embarrassing than it sounds. But it is being temporarily fixed to install a new hard drive. I can't remember the last time I didn't work or use a computer everyday. So I need to get it fixed- fast!
