I've had the mac that's outlined in my signature for three days, it's working great, but every once in a while it seems to completely lock up, that is to say i can't click on anything, the program that's running at the time of lock up will display the spinning thinking wheel. If I pull up a folder with lots of stuff(like the applications folder) it takes forever to populate exactly what's in the folder. I shut everything down, and i mean everything that was running as a program and launched "Age of Empires 3" without any addons to the game. Every time an NPC voice has a part in the game the game basically freezes up and then resumes. I thought maybe my drive was too full, but out of 250GB only 44 is used, and 25 is dedicated to the WindowsBootcamp side... is my Harddrive bad?
