A motherboard which can play an image or a video in a power-off state is disclosed. The motherboard includes a circuit board, a north bridge chipset, a digital photo frame chipset, and a switch unit. The north bridge chipset, the digital photo frame chipset, and the switch unit are disposed on the circuit board. The digital photo frame chipset is activated according to a stand-by power in the power-off state. The switch unit is electrically connected with the north bridge chipset and the digital photo frame chipset, respectively. The switch unit electrically communicates with the north bridge chipset or the digital photo frame chipset according to a triggering signal. The motherboard may utilize the stand-by power in the power-off state to display an image by a display device via the digital photo frame chipset and the north bridge chipset when a computer system is powered off.
