I just bought a Geforce gtx 550 ti today because my last card was showing green and pink lines after it crashed as i played a game. I thought my problems were solved, but after about 30 min of game play the game crashed and the pink and green lines returned. They go away after i put my pc to sleep the wake it again , but i have no idea y this is happening. Please HELP me!
try reinstalling drivers. Also check the gpu temperatures.
If problem persist after you install new drivers, you most likely have a bad card that need to be replaced.
Il try that now, but i dont get it some games like Skyrim run on ultra just fine and no crashing but like saints row 2, crashes in 30 min and lines pop up. and my card runs at about 33c not running games and about 45c to 50c when running games on high.Also could it be possible that my new card has the same problems as my old one?? seems kinda weird dont u think
