apple macbook pro a1286 boot looping after update

Tried booting from external drive same problem. I have an identical machine with the same issue.

Just removed the SSD Drive an booted it on an other Mac. Has anyone encountered a similar problem with their MacBook Pros? I don't think it is the wide spread El Capitan Boot Freeze I'm afraid it is a hardware problem :-( A horizontal stripe of artefacts (see Screengrab) appeared quickly and the black screen followed by a white screen an the fans starting to run on max speed. Today same glitch but but the MBP shut down after pulling the display cable! On trying to boot, the Apple Logo appeared and the progress-bar went halfway through. I blamed it on a faulty display cable or the external screen itself. It started a few days ago when I had two glitches where the external display would show the left half of the screen on the right side and the other way around. I tried resetting NVRAM and booting in Safe-Mode.

I've got a wicked problem with my MBP early 2011 El Capitan (high-res display 1680x1050 pre Retina).Īs stated it crashes half way through the boot sequence.
