Idk the technical term for it but i will get all types of random lines all over my screen all depending on where im looking in my game, it doesn't do it 24/7 for it will do it if i find a certain point, i bought the gpu used, its a Gigabyte R7 260x. So im wondering if the gpu is on its way out, when i ran HWmonitor it was reading 113 degrees at one point, i dont get how its getting that hot when i have good airflow, 3 fans on it and every other part of the computer is cool
