I have a very weird problem. While I am at desktop and leave computer unattended my screen goes black after 1 minute. However, my monitor stays opened i.e. it does not go hibernation. I checked everypossible thing but no solution. Uninstalled/installed my graphics driver, closed every open program on task monitor no change. Even there is no graphic driver installed on the computer it is the same.
Win 7 ult.
