Weird screen problem and freezing.
My MBP has started to get some weird pixelated distortion that goes on and off in intervals. It started yesterday and during that time the computer froze twice and had to be restarted.
When my computer restarts it always shows a black screen with a lot of text, it was like that since it came back from apple for repair last time, even under this startup mode the pixelation occurred.
I don't know if it's connected but a moth back or so I got this weird blue screen with horizontal lines and I had to restart that time to. Only happened once though.
Anybody knows what this is?
