I was working on my laptop (inspiron 1420) the other day when the screen went white. Suddenly black spots started to "grow" on the side of the screen and spread throughout. I've been looking around for a possible reason/solution for this but I haven't found too much info. I've posted a video (sorry about the quality) but it shows exactly what happens every time I boot up now.
