I. Common Issues: 1. Loud Power Supply Fan Noise: Due to prolonged operation, the computer power supply fan may accumulate dust, causing it to run poorly and produce noise. 2. Unstable Power Supply: This may be caused by aging components inside the power supply or damaged power cables. 3. Power Supply Failure to Start: The computer cannot start normally, which may be due to power supply failure or internal circuit issues. II. Solutions: 1. Loud Power Supply Fan Noise: - Clean Dust: Regularly clean the dust from the power supply fan to keep it running smoothly. - Replace Fan: If the fan is damaged, replace it with a new one. - Add Lubricant: If the fan bearings lack lubrication, add some lubricant. 2. Unstable Power Supply: - Replace Power Supply: If the internal components of the power supply are severely aged, it is recommended to replace it with a new one. - Check Power Cable: Inspect the power cable for any damage or breaks, and replace it if necessary. - Ensure Stable Internal Connections: Ensure that all connection lines are securely connected to avoid poor contact-related power issues. 3. Power Supply Failure to Start: - Check Circuits: Inspect the internal circuits of the power supply for any abnormalities and seek professional assistance for repairs if needed. - Replace Fuse: If the power supply fails to start due to a blown fuse, replace it with a new one. - Check External Devices: Ensure that all connected external devices are turned off or unplugged as short circuits from external devices can sometimes prevent the power supply from starting. 以上就是电脑电源常见问题及解决方案的详细分析，希望对大家有所帮助。
