The contents of video ram aren't initialized by the hardware. They just come up in a random state are and just going to be overwritten--why would the video card both to zero it out? In this case, the contents of video ram just happens to be the "ghost picture" you are describing until it gets overwritten. The image in the video ram will persist through a reboot because there is nothing actively destroying it's contents. -- Wesley J.
