My computer is gone....it turns out it wasn't anything I had done-thank goodness!
The mac guy said that my RAM was fried and that was why my PSE6 would keep crashing on me.
Due to the ram not working when I tried to reinstall my operating system (leopard) and tried to archive my stuff that is why computer stopped working and I lost EVERYTHING on my hardrive.
THANK YOU to everyone for your help and suggestions- and to all those ladies who left me awards :) thank you so much!! But I'm going to have to wait to post them as I don't have a mouse to copy and paste :)
