I've been getting distorted black edges on the left side of my CRT monitor for the past week. Also, these distortions aren't always there. They just pop up randomly. Sometimes they stay in the upper left corner of the screen, but at other times they run down the entire left side of the screen. Adjusting the monitor's settings doesn't do much either. The distortions move with the rest of the image. Is it my monitor or my video card that needs replacing?
Sorry the picture's a bit blurry, but you get the idea. =/
