Since 6 Months and after upgrading my GPU to GTX 1050 ti from GT 520 i started getting horizontal lines on top of screen, each a period of time i get a new line ( now 4 lines) , they are very annoying, the FPS is pretty good and my CPU isn't causing any bottleneck to my GPU but those lines are very annoying, how can i get rid of them ?
i'm using an adapter vga-hdmi and my monitor's refresh rate is 60Hz.
