Not sure exactly when this started, but lately my monitor will flash on and off...It does this a lot when I try to turn on the computer, but also does it after using it for a while it will start to flash on and off. I can get it to temporarily stop by turning off the monitor, and if that doesn't work I can pull the plug and put it back in and that will stop it for a while. Does anyone know of a more permanent solution? I want to try all that I can before I have to go out and buy a new monitor. Any help is appreciated!!
