Whenever i turn on my computer from sleep mode my monitor is all green like this color and then returns to normal after a few seconds, it used to do it every once in a while now it does it all the time...i have no idea if my graphics card is going out or if its my monitor. If someone could help me out that would be great!

I'm not an expert, but in BF3 I found that intermittent green flashing was artifacting from my GPU getting too hot.
