I have been having issues with my  MacBook Pro freezing for about 4 months now, since I upgraded to Mountain Lion, although I'm not sure if that is the cause.  I get these horizontal barcode like flashes of black across my screen and then all the graphics freeze, but my music or movie might still be playing, although I cannot access anything.  The only way to get out of the freeze is to hold down the power button.  I'm not sure what is going on at all, but I've tried switching from Chrome to Safari to Firefox.  Didn't work.  I've tried switching off my flash player; it still freezes.  I'm really stuck, and the constant freezing is really detrimental to work, so if anyone has any ideas, that would be so greatly appreciated!  I'm not always sure how Etrecheck works, but after my computer rebooted this is what showed up:

    Certainly sounds like a graphics card problem-  Hardware

    Well disappointing feedback from Apple Support.


    You can try running the (AHT) Apple Hardware Test yourself. Not wholly adequate  or complete but something.


    Reboot holding the D key to get to the AHT.




    report back any error codes.
