Q: macbook webcam stops working and causes the startup issue
My built-in webcam on macbook pro 2011 suddenly didnt work. Now when I turn on computer, after the apple logo screen, it gets into a blank white screen. I have to turn off and start it by holding the power button several times and it finally boots successfully.
however, when I start any applications which access to the webcam, the screen appears many stripes, the computer stops working and I have to reset by holding the power button. Again it follows the process above: turns to white screen -> reboot by power button several times and success. this time, I try open a webcam application again, the screen turns to blue and again, the same process: reboot by power button > white screen -> reboot several times -> success.
I tried booting to windows, it successfully boot into windows desktop. after about 5 minutes, many striped appears on screen and it stopped working and yes again, the same process as above.
Now I'm in MacOS but I don't want to try openning any webcam application and I don't know what will happen after I restart the computer.
MacBook Pro, OS X Mountain Lion (10.8.4)
