    This is my very first porblem with mac hardware.

    I launch a game, 1-2 minutes in I hear a very faint sound and screen goes black, I can replicate this everytime I open a game. If I force integrated, this does not happen, so its a problem with the 650m.

    tried with wow and civ v.

    This just started happening today without any obvious reason.

    Ayone had anything like this, do I just have to take this thing in, anything I can try to fix it?

    Okay, it also happens with cinebench, so anything taxing on the dgpu.

    This actually started happening right after I downloaded an airport utility update from mac app store, this cant be related with that though can it?

    EDIT: Booted to windows 8, screen goes black on live tiles after 30 seconds.

    Here's the report:

    It seems that the issue is really with the dGPU. Try using gfxCardStatus to force the dGPU and see what happens. It will revert to normal after a reboot so don't worry.

    You should also try doing an Hardware Test:

    Said no hardware problems found. Although after the test it booted to a black screen and had to restart it. Didn't do the extensive test though. I'll backup this thing tomorrow and call apple on monday.

    Try the extensive test. But yes, you will need to go to Apple anyway.
