Hi, I have recently bought a Gigabyte GTX 770 2GB and when I run heaven benchmark i find things like shining colorful stars in some parts of the benchmark and also, in some games like ac 4, horizontal lines appear. I haven't overclocked it and i have tested with the serie drivers, with the nvidia most recent drivers and with beta drivers, and all the time I receive the same thing. Can you help me and explain what is happening?

Thanks for your help.
