When a personal computer experiences a sudden malfunction with no apparent cause, it’s crucial to prioritize a thorough examination of the power supply unit (PSU) when troubleshooting the system. A malfunctioning or faulty PSU can manifest in a wide range of intermittent computer problems, such as random shutdowns, boot failures, and system instability. Experienced PC technicians often consider the power supply as a potential culprit and begin their diagnostic process with a comprehensive assessment of the PSU’s functionality and health. Common hardware-related issues that can occur with a computer system include failures during the boot-up process, the PC not powering on at all, spontaneous restarts or lockouts when trying to use the machine, case fans and hard drives that do not spin, an overheating system due to heatsink and fan failure, errors related to system memory, and recurring blue screen of death (BOSD) errors. These issues can indicate various hardware malfunctions that may require troubleshooting and repair.
