A multimeter is a device that measures voltage, current, and resistance and can be used to test the power supply.

Replace the power supply: 

If the power supply is not functioning properly, you may need to replace it. Make sure to choose a power supply that is compatible with your motherboard and has the appropriate wattage to support your system.

Check the system components: 

If the power supply is functioning properly, you may need to check the other components in the system to ensure that they are not causing the issue. Make sure that all of the components are properly seated and that there are no loose or damaged wires.

Troubleshooting the power supply on a motherboard can be a complex task, and it's important to have a good understanding of the system and its components to effectively diagnose and fix any issues.
