This problem's existed for a long while now. If I run any 3D game or program that has a high poly count - that is, any modern game - after between 1-10 minutes the computer will freeze up, and green vertical static lines will appear across the screen.
Old games such as the original Half-Life do not cuase a problem.
I updated my graphics card driver and made sure I had the lates DirectX, but the problem was (and is) still there.
What's most likely at fault? Inept graphics card? Power supply too low for the card?
