i have an older powermac g5 running OSX 10.5.8 with two volumes. volume 1 will not boot past blue screen. i can however boot up from second volume by making it my start-up disk, but am unable to access files (which i desperately need!) from volume 1. i "see" them there, but the applications will not open--some try, then crash. i have run disk utilities, reset pram, and a ton of other things and all check out okay, yet still stuck at the blue screen when i try to boot as normal. i do not have the install disks, and the optical dvd drive stopped reading disks a few months ago. (yay) any help would be appreciated... PLEASE!!!
