Regarding apple.stackexchange.com/questions/148868/macbook-pro-early-2011-sound-loop-black-screen
It happened again and it's the 5th time in one month. Everytime I play youtube videos on Safari only the screen just freeze and the fan gets much louder.
I forced it to shut down and when I turn it on again I got black/grey/blue screens..
Is the Flash Player the main source of problem here? I updated it to the latest version.
