A method for looping images on a screen of a computer and a method for checking the operation of an advertising application program re disclosed herein. A graphic chip set (13) is programmed with image data to be displayed and an image position control signal form a system BIOS (12). The graphic chip set displays a desired image on a desired position of the computer screen. The displayed image is looped at a predetermined period under control of a main board chip set timer (11). The main board chip set timer periodically applies an SMI control signal to the system BIOS, which then checks the operation of the advertising application program (15). Upon receiving no response or an abnormal response from the advertising application program, the system BIOS stops the operation of a system, compulsorily re-boots the system and requests the user to re-install the advertising application program. |
