My daughter’s 1 yr old Dell laptop began showing the odd screen artifacts that you see in my attachment. It is as if someone took a marker and scribbled on the screen. She says it is not always this exact form, and does not seem to interfere with normal use of the computer. She is using Windows XP. She lives in another state so I have not seen the problem first hand; I am just trying to narrow the problem down for her. Any thoughts? Thanks.
