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. The other end of the resistor R3 is connected with the base of the triode Q2 and the collecting electrode of the triode Q1. The emitting electrode of the triode Q1 is connected with the resistor R1 and grounded. The computer internal module voltage processing circuit firstly transforms the power VCC into square signals, controls a boost circuit switch to boost the voltage, and finally outputs dynamically stable voltage. Transformers are not used in the computer internal module voltage processing circuit, and therefore the problem of strong electromagnetic interference brought by the voltage boosting circuit which is based on transformers is solved.
