Voltage adjusting system and method for motherboard components of a computer

A voltage adjusting system for adjusting voltage values for motherboard components of a computer, comprising:

• a voltage regulator configured for adjusting a voltage of a motherboard component based on an adjusted voltage;
• and
• a basic input and output system (BIOS) comprising:
• an input module configured for receiving the adjusted voltage of the motherboard component, and providing the adjusted voltage to the voltage regulator;
• a voltage detection module configured for determining whether the motherboard component works abnormally under the adjusted voltage;
• and
• a voltage record module configured for receiving the adjusted voltage from the voltage detection module, and storing the adjusted voltage in a memory system upon a condition that the motherboard component works normally under the adjusted voltage;
