So recently, I started getting horizonal lines on my monitor and after a while playing a game, my screen froze with the whole screen filled with black and white horizontal lines. I have a msi r9 270 and cruciel sports ram ddr3 1600 cl9 16g. I tried changing monitor and still get it, however it was only a flash of lines, it has not freezin. Could you guys tell me what is wrong? I only had mycomputer for 2 months.
