I have noticed that the left side of my laptop's screen turns a light red when on pages with a white background. It is about a fourth of the screen that turns light red. This just started happening today.
Try booting up in a different OS, like with an Ubuntu boot CD. If the screen is still funky it's a hardware problem and you'll probably want to take it in to the shop. If not, it's probably a software problem and you should try updating your drivers or possibly reinstalling your OS.
