Hey everyone, my spring 2009 aluminum-body macbook is showing some odd behaviors. Right now, it is running on 240gb with 4gb ram. The problem is as follows: Whenever I open certain programs, they randomly shut down or just break-down. Some of these issues include: when I try to edit a picture in iPhoto, the program shuts down. when I try to print in microsoft word 2008, the program shuts down and sends an error report. when I try to open GarageBand, the screen reads 'initializing' before the program simply shuts down. I downloaded Skype from the internet, and when I accept the terms and agreements the program shuts down. I have no idea where to start with this...At first I thought it might be my iLife (i'm running snow leopard) but a fresh reinstall did nothing. I thought it might be the fact that I upgraded my memory, but I realized that it probably wouldnt make sense that a memory issue would only cause certain program failures... Otherwise, the computer is running perfectly.... So, I come to you geniuses...any help? I would really liek to have a complete computer, up and running, without any app. issues... Thanks in advance!
