These weird horizontal and diagonal lines flicker across my screen after my PC has been on for a few hours, they appear and reappear intermittently. I have taken and put back in the cables connecting my monitor and my GPU and it still doe sent have seemed to have fixed.

I have a ASUS GTX 970 STRIX and it is connected to the LG LED Monitor with a vga to dvi converter.

heres what it looks like: http://imgur.com/RNLTD2D
