Hi there. Whenever I play WoW, my computer always freezes up, and the sound starts to repetitive click. I can't move the mouse, even if I'm playing in a window. I always have to force quit my mac by holding down the power button for 5 seconds. I have the new MacBook that came out earlier this year, the aluminum one. The crashes usually happen when i go into an arena, on my rogue. Please help!!!
