My screen appears to ripple when I try to scroll down. Not sure whats causing it, anyone got any idea's how to solve the problem

it is your driver you need to download software that will run your graphics whether its built in or not. you should have a disk for this and if you dont go on nvidia or radeons website and download the driver for it... you also might need to update if you already have and if its built in it can only be on the disk, Ross
