Recently when playing the new assassins creed, my screen went black for a minute or so and then reappeared with green horizontal lines all over the screen, the hard-drive also got set out of wack and I had to re install windows.

I have got the hard drive to work again and everything is great other than the graphics cards that is still having problems with various artifacts and these green lines. I am a student and I cannot afford to buy a new graphics card so I want to give a shot at fixing it, so I have done some research and it all looks very complicated.

I ask here if anyone would have any idea at all of what may be the issue with the green lines or what may have causes it, just so I know a bit more about what I am looking for when it comes to finding a way to fix the card?

Thanks so much for your help, I really appreciate it.
