Power Supply Troubleshooting
Power Supply Troubleshooting refers to the process of diagnosing and fixing issues related to the power supply unit (PSU) in a computer system. The PSU provides the electrical power needed for the various components of a computer. Issues related to the power supply can lead to system instability, unresponsiveness, or failure to power on. Common steps in power supply troubleshooting include checking for loose or damaged cables, verifying the PSU is receiving power from an outlet, testing the voltage output with a multimeter, and replacing a failing PSU with a known working unit. In some cases, issues with other components may mimic PSU issues, making it important to thoroughly investigate all possibilities when troubleshooting.
