    Hi. I have a Mac Pro 2012 with Yosemite installed.

    Recently on boot up, I get a screen full of crazy colours and lines (can supply a picture if required).

    I adjust the screen either up or down slightly and it seems to right itself.

    Could this be the result of a loose or faulty graphics card/cable?

    I did an extended Apple Hardware Test (AHT) and it came back with no errors.

    Thanks.

    So what's the solution?

    It's a new (enough) computer- surely it's a fault of some kind.

    It's a Macbook Pro. Model A1278.

    Sorry maybe I've posted this in the wrong forum.
