Has anyone seen this happen when shutting down XP Home Edition: * You click on "Start" then * Click on "Turn off computer" and * A window pops ups to turn off the computer And you don't click on anything for a while, you just leave the window there without turning it off, and the monitors colors fade slowly and turn to black and white. As if you have B&W, no color. If you click on "cancel" the color comes back. Or, I'm thinking it could be the Matrox quad card causing this. Thanks.
