Hi everyone. I have a macbook pro 15" 2007 with an nvidia 8600GT. A very strange thing started happening today; random graphics glitches have started appearing. First, on certain parts of the screen, the white border around the mouse cursor turns a shade of purple. Also, when you open or close a finder window, a few frames of the the animation turn purple. This has never happened before, and I can't think of any recent updates or programs that could have caused the issues. The issue persists even after a reboot. Pretty minor issues that I can live with, but is it possible that my nvidia graphics card is starting to die?
