I am experiencing a problem where my computer locks up when I go to change the display settings. I have loaded a Scrabble game that says I need to change my colors to 256. Once I made the change the computer locked up. When I restart it works fine but whenever I go in to change the settings it locks up again. I have reinstalled the video driver, defragged, booted in safe mode and reinstalled the driver, uninstalled the Scrabble game but it is still happening. Any ideas?
