I have a Windows 8 Dell Inspiron 660 with a GTX 750 ti graphics card. Last night, I was playing EVE when my screen got overrun by flashing colored lines that made it impossible to see. It happens randomly when gaming or on the desktop. I know cables are not the problem for I wiggled them when the screen was normal and no flashing occurred. This happens predictably when I try to play a music file or open a webpage almost every time. For some strange reason turning off the monitor and turning it on again temporarily fixes the problem before it inevitably happens again. Any help or insight on what this means would be greatly appreciated.
