My friend's MBP was working just fine when suddenly... this flashed on her screen.
She turned it off and waited a while. It powered up just fine and then the screen froze and these black vertical lines showed up.
What does this mean? Can this be solved? Is it in need of Apple specialist? It's running the Leopard OS X. I am not sure which exact version though.
