I have a late 2006 macbook pro (2.0Ghz CD) and I believe I am having problems with the video card, the computer freezes randomly, however I am able to move the mouse. I am also getting little lines of different colored pixels randomly, they show up on a screen cap so I know its not the screen. I was wondering if a reinstallation of the firmware, or a revert to the original firmware would somehow fix my problems. I do not have applecare so that is out of the question.
