Blue Screen Of Death

Ok, so I have started to get back into crossfire as I have my nans laptop. But I have an issue, After about 30 mins of playing the game, (whilst in a game) the screen blurs, and the blue screen of death comes up. I cannot get any screenshots as the computer turns off and it will not save what I captured. When I say that the screen blurs, I mean that I see a number of copies of object across the screen. eg: My gun will have the real thing in the middle, with others across to the left. Kind of a drag type thing. If you could help that would be great.
