My computer is a little old...but it still works great... 800MHZ iMac 256MB RAM 80GB HDD OSX 10.4.(newest) I booted it up this morning, logged in, and my background loaded but finder didnt... Ive had this computer for awhile now and its never done this bafore...its has a lot of pictures and important files that I CANNOT lose...id atleast like to back these up and reinstall-10.4 or 10.3.... Anyone have any ideas? I also have a Ubuntu Boot Disk for PPC, if I needed to load an OS to back up files, but i dont know how to change my computer to boot from the CD drive..is there a way to get into the BIOS or something like that???
