I am running a Gateway mid tower PC, P4, 256 RAM, WinXP home. Whenever I boot or reboot the computer the display setting automatically changes to 640X480 (Low 8 bit) from 800X600 (Highest 32 bit). I can go in to the display and change the setting back but I must do it every time my computer boots. Can anyone suggest what causes this or what I can do to correct this abnormality. Thank you, John
