So, my GPU (GTS 250) has these static around the screen, much like a cable tv set with bad signal (if you visualize that). I dont understand why, is there not enough power or is something broken on it? I have dusted it and put new thermal paste on it to see if it was heat, still the same results, would underclocking/undervolting it work? I had to get a replacement card for the meantime to deal with this. Thanks for any answers.
