My laptop is a toshiba satellite A300-1m1 and I'm using an ATI radeon mobile HD 3470

Here's an example of the problem: http://img69.imageshack.us/img69/7011/29467894.jpg

I've tried turning it off to cool off, uninstalling and then updating the video drivers, turning the color color quality settings from 32 to 16 bits ( they disappeared but came back when i opened 1080p video files )

Any ideas?
