Well, I hate to say it but I have had more system craches (kernel panic) in the last week (on my mbo 2.16) than I have had in 5 years of owning a custom-built PC....unfortunatley. I have had 4 in the last week, and have no idea why!!! It is very scary considering I am in medical school working on my computer all the time. I have lost important presentations - kind of frustrating. Anyway, what route should I take to get this problem resolved?? I feel like if I take it to apple, they will say that there is nothing wrong. I have also had reoccuring issue with a fan or HD noise that I can't seem to figure out...hardware test says everything is fine, and I can't induce the sound , it just happens radomly every other day or so. Any suggestions?? I would be very greatful, thanks. I am a first time mac guy, and still like it very mucg, but I just cant afford to have all these problems at this moment.
