This is on a Dell Vostro 1500 laptop, running windows 7. When using the computer it seems as if someone took a picture of the screen and left that up for a few seconds, or if I move the screen it will go back to normal and work fine for a little bit. When this happens everything still works and I can even see the mouse move so I dont think its a problem with memory. Like if I was typing a paper or IM it would still go as normal I could even surf the web if I memorized exactly where to click. So does anyone know whats going on?
