tayklor Posted March 21, 2008 Share Posted March 21, 2008 OK, I have a 1 GHz TiBook and one in every 5-10 times you start it up, the video has a fine grid of black through it. You can shut down, press the P-Ram button under the keyboard and it works fine again. If you know anything about this please help.
