I have a major problem

Ok, a while ago I changed the setting for Defcon, the Graphics setting, and sadly I forgot which one I changed. Anyways, what happens is every time I start up defcon the screen turns black and stays black and my monitors green light turns yellow. I can still hear the sound of menu and even when I minimize the program the screen still remains blank and doesnt return to normal until I close Defcon with Alt+F4.

Deleting Defcon's preferences.txt file will restore default settings. The location of said file is normally C:\Program Files\Defcon but it may different for some versions of Windows and/or if you have the Steam version.
