My Macbook Pro has been making a weird screeching noise. It will make the noise and freeze so the only way to get rid of it is to leave it until the noise stops(usually like 30 seconds to a minute) and then restart it using the power button or restart it with the power button while it's making the noise. I did a quick google search and this video is the exact noise it's making. http://www.youtube.com/watch?v=6vB5GyWVi3c Any idea what it is? I'm not under apple care anymore so I don't want to take it to apple without knowing what the noise is and if I can fix it myself or if I should just pay to have it fixed by them.
