I have a Toshiba laptop. It's never been dropped, banged, hit... or anything like that. One day, these lines appeared. It starts at the top and ends at the bottom. I tried to take a screen shot of it... but the lines don't show up in the screen shot! They are always there... while I'm watching movies, when I'm typing this right now, when I'm playing games, when it's just my desktop.
Anyone have any idea what they are from... and how I can get rid of them?
