Here is my set-up 15" PowerBook 1.67Ghz, 1.5gig ram, 100gig HD. This is the model that come out last febuary. 2 days ago i noticed that Quicktime Pro (7.0.3) was acting up and crashing a lot. So i repaired permissions and no improvement. SO i booted to the OSX disc and ran disc utility. An info file was currupted and could not be repaired by Disc Utility. So out came the trused Disc Warrior CD. it would not boot so i grabed the latest update....but that would not boot either. So I installed OSX on a FW drive and install Disc Warrior. I repaired the the laptop drive using the external drive installation. So nothing really improved. Safari would crash every time i tried to view a video file in Safari or when exporitng to quicktime from After Effects (which i really need to work this semester). So now i am in my trusted "Test" acccount that I created months ago to see if stability improves. If it ends up being a account issue then what steps should i take to fix it. Should i creat a new user account for my self, movemy files and chown them? Thanks in advanced.
