I recently bought one of the new Macbook Pros (2.5 GHz, 4 GB RAM, 128 SSD), and it runs great, except for when I play any graphically intensive game (notably Age of Empires III and Portal in Windows). Every time I try to play, there comes a point where the screen suddenly goes completely black (turned off), and everything becomes completely unresponsive until I reset. The system does not crash, because I can still hear iTunes and/or the game audio playing, but nothing responds. I don't think the issue has to do with overheating, because sometimes this occurs within a minute or two of loading the game, and before anything gets very hot. Has anyone else been having this sort of problem, or have an idea as to how I could fix this issue?
