Hello, I have this weird problem. I have Nvidia 9500 GS, and I play CS:GO. The game itself runs from 80-110 fps but suddenly pink and green curved lines appear, sometimes just pixels. I have checked my temps, GPU is around 57 C in game, and cpu around 55 C. I thought it was overheating so now I run it at 100% fan speed. I am able to play for 30 min only if I open my window all night so that cool air can go in. Is it overheating or not, because I have read that these temperatures are quite normal for a GPU ? I have tried even with other games and here's what it looks like : https://www.youtube.com/watch?v=xTdNF6bwl0k
