my brother was trying to play a dvd the other day on his comptuer. the palyer said it can't play under the current 1024x768 resolution so my brother changed the resolution, after he restarted his computer, the computer would POST, the windows xp loading scrren would come up but windows itself won't display on the monitor anymore. you hear the startup sound from the speakers but the screen is just black. I tried a different monitor to the same result. Any ideas??
