    A friend of mine has had this recurring problem with her MacBook Pro and I don't seem to find the source of the problem. At first I asked her what she did before that happened, and she told me she was on TinyChat. I told her to reboot and to check other services that use the camera. The camera worked fine on Photo Booth, Facebook, and Tumblr. Even TinyChat. So I ruled out TinyChat as the possibility to the problem. I haven't told to her to Repair Permissions because I want to know if there's something else causing this, and it's better if she doesn't flick around with not-so-novice things. After the TinyChat test, she continued using her computer but after, approximately, 2 hours later, it happened again. What could be causing this? A faulty GPU? I told her to go the nearest Apple reseller (no Apple Stores here) and try to find help there. She still hasn't gone.

    What's the CPU and GPU temperature when that happens?
    How often does this happen? Once a week, many times a hour?
    Also, does it happen only with a particular application?
