Hi guys, I bought a macbook pro about a month ago through my school. Basically, as soon as I got it I noticed it seemed to crash whenever I had several programs running an once, or if I was playing a game such as Cod4. I took my computer to the tech guys at my school and they said they would re-install all the software and check the hardware (the name for this escapes me at the moment). I got my macbook pro back today and as soon as I got home I opened up two word documents and a garageband project for an assignment I was working on... and my macbook proceeded to crash... I am just wondering if there is any way I can get this to stop, and if anyone else has the same problem. Maybe I need to take it to Apple? My macbook pro is standard late '11 model running OSX Lion 10.7.3 and is the 13" model. Thankyou for your help ---------- Aha, just remembered my computer was 'rebuilt'.
