A method for executing computer function option with intelligent memory is provided, including loading the multimedia application program corresponding to the pressed function option button into the image file memory region of the system memory for execution when detecting a function option button is pressed. When the user shuts down a function option, the multimedia application program stops execution and is stored in an image file format into the pre-determined memory address in the data storage. When the computer detects the same function option button being pressed by the user for activation, the computer loads the program image file corresponding to the function option button into the image file memory region of the system memory, and executes the program image file.
