A computer system includes a north bridge chip, a power source, and a resistor-capacitor filter circuit coupled between the power source and the north bridge chip. The north bridge chip has a digital-to-analog converter analog power pin and a digital-to-analog converter analog ground pin. The power source is coupled to the digital-to-analog converter analog power pin of the north bridge chip. The resistor-capacitor filter includes a first resistor and a first capacitor. The first resistor is connected between the power source and the digital-to-analog converter analog power pin of the north bridge chip. One end of the first capacitor is connected to the digital-to-analog converter analog power pin of the north bridge chip, and another end of the first capacitor is connected to ground together with the digital-to-analog converter analog ground pin of the north bridge chip.
