I was running an older multi media cd on my powerbook 4 OS9 began to load. I believe it has osx panther anyway it loaded up and all the graphics became pixulated. I tried to eject the disk but it said it was in use. I eventuallly forced shut it down. Now I am having trouble booting it up. Noithing on the desktop and the gray bar on top does not load. I went through a few of the thiongs on the Mac site for trouble shooting but nothing has helped. Any Ideas thanks a lot
