You need to give more information about your operating system and hardware to get a good answer. I will assume you have a legal copy of the game.
This is one of my favorite games of all time, and it can be tricky to get to run on newer hardware. I seem to remember that when I got a new computer with Vista, I had to disable movies to get the game to run. There is an option to do this in the graphics settings I believe. I also remember something about having to update or modify something about the sound.
Anyway, search google for "KOTOR 1 and Vista" or win 7 or whatever you OS is. Also take the standard steps of trying to run in XP compatability mode and updating your drivers and patching the game to the latest version.
