I own a 13" Macbook Pro and have recently installed Windows 7 on it. I ran into a lot of problems at first, namely no sound. Thanks to some searching I found a fix and now the sound is running fine. But whenever I try to run a game which requires 3D rendering (in this case StarCraft 2) I get a message that says "The videocard was not accessible because no display drivers are installed, another 3D application has exclusive access or the machine was locked." Now obviously this is frustrating since the main reason I installed Windows 7 was for the increased game selection. I've tried looking for drivers, but even ones from NVidia aren't helping. All they claim is that I have no compatible hardware. My graphics card is an Nvidia GeForce 320M. Any help?
