Frozen macbook pro, late 2011 model, rebooting to a blank white screen
Hi
I am using a macbook pro, late 2011 model. I bought in January 2012, have been using it all the while until yesterday 26th April 2013 with no problems at all. However, as i was watching a movie, the screen froze, with a weird red checkerboard pattern all over. When i tried rebooting it, it was fine at first, but then the horizontal lines appeared across the screen, and the computer froze. Then i had to reboot multiple times as i kept getting a blank white screen.
I am really unsure of what went wrong, so i searched for apple software updates, and there was a java update available, so i installed that and turned the laptop off. When i turned it on again, i watched youtube a couple of minutes, and when i tried to open a video, the screen froze with black horizontal lines again, and it refused to boot - just stuck at the white screen after the on chime. Does anyone know what happened to it? I really don't want to spend thousands on repair cost after all the laptop is still very new.
MacBook Pro, Mac OS X (10.6.7)
