| "Safe mode" is designed to be a user usable way to start up a PC. Its purely designed to help you fix something if its gone wrong, like a badly installed driver.
What it normally does is load as few drivers as possible, and tries to use default drivers as much as possible, IE Using the basic VGA driver instead of your wizzy graphics card driver.
DO NOT use this for general computer use, if you find you are having to you may need to reinstall windows.
