The invention discloses a computer internal module voltage processing circuit. The circuit comprises a resistor R1, a resistor R12, a capacitor C1, a triode Q1, a inductor L, a diode D1 and a triode Q2. One end of the resistor R12 is connected with the inductor L, a power VCC and a grounding capacitor C3 respectively. The other end of the resistor R12 is connected with the grounding capacitor C1, the emitting electrode of a triode Q5, a resistor R5, a resistor R6, the collecting electrode of a triode Q3, the emitting electrode of the triode Q2 and a resistor R3.
