In a method of processing an abnormal digital/analog convertor (DAC) of a video card, the video card comprising a first DAC and a second DAC, the video card connecting to an output interface. The method controls the video card to use the first DAC for converting data to the output interface through a first switch and at least one second switches in the video card.
