Hi everyone, I have a 15" aluminum Macbook pro, which I purchased less than 2 months ago, everything up until now has been running perfectly, but lately I've had a little problem. Every so often my screen will briefly turn off, and i see a black bar at the top of the screen, this all happens really fast, less than a second. It kind of just flickers really fast. It happens when I'm using battery, as well as when I'm plugging in. This happens around 3 times a day, from what I can recall, and it's been happening for around a week now. Anyone know what this can be? Should I be worried, because I kind of am 
Thanks a lot.
