Did my graphics card explode?

[JaJaWa]

So I've noticed that in Photoshop, the part of the window showing the document I'm editing sometimes goes all blocky when I apply an effect and I have to save the document, then close Photoshop and open it again. This doesn't happen with the nVidia graphics card disabled.

Earlier I tried to plug an external display in and my Mac just goes blue and the display doesn't show anything. If I pull the display out, my computer is totally unusable.

Photo attached to show what happens.


I'm wondering, has my nVidia graphics card exploded?


Already had the screen swapped on this MacBook due to IR, specs below:

That's odd. It almost seems like a GPU failure. I'd take it back in.

Try to reinstall the software. if it doesn't work, go to genius bar. I haven't seen this problem before.
