Notebook, Desktop? Flat screen? Could be the monitor or the video card. There is a program you can use it called BurnInTest. passmark.com You can stress test the video card to see if its failing. If its a desktop swap out the monirtor and see if it does it on another. If its a notebook, use the software I provided.

If it is a CRT... If “localized” then the tube's screen has been partially magnetized. New speakers or speakers too close to the screen's front? Move them away, and subsequent COLD starts should clear it up. I emphasize cold as in off for a while so the de-magnetizing circuitry can cool or reset to properly function when powered up. Repeat as necessary. If “overall” then the tube or drive circuitry (transistors) or both is showing signs of age. Probably shouldn't happen on a flat screen. Id Edit: If "overall" (CRT or flat screen), It may also be the video card or a change in the "color temperature" or "gamma" settings".
