Right so my Graphics card has this problem. While gaming it will give strange flashes all over my screen, they almost look like fireworks and in varying colours. Now and again it will also give out a blue checkerboard over textures. Every single time it will jump and stutter and eventually either CTD or freeze my whole PC resulting in a hard reset of my whole PC. Temperature wise it isnt going above 65 centigrade. The card is also only 9 months old. My gut instinct is saying the card is F****d but what do you guys say.
