Graphics issue

[bpg2012]

Everything was normal then 1 time i logged in and it looked like this i have no idea what happened it just randomly started looking like that and i'm not going to even wast my time with disney because they do absolutely nothing any tips on fixing this would be great

p.s thanks in advance

And now 1 day later at random moments the screen will go completely black and the game stops working and in the bottom right corner it say "the igfx display driver has stopped responding and has suxessfully been recovered" ( i just installed a update for my graphics media accelerator intell 965 ship set family )
