I think your video card is fucked up . I know because it happened to me before. ı had got a 5700le. ı put an aftermarket cooler on it but it had not been contacting to the gpu( ı learned it when it was too late) ı was overclocking it and after a while thouse vertical lines appeared even in bios screen and my video card was dead
