With the development of technology, computers have become an indispensable part of our daily lives. As the foundation of computer operation, power supply failures can cause inconvenience to our work and life. Therefore, mastering the skills of troubleshooting and repairing power supply issues is an essential skill for every computer user. I. Common Signs of Power Supply Issues Power supply issues can manifest in various ways, such as computer not booting up, frequent restarts, slow performance, etc. These issues may be caused by power supply problems, so we need to carefully troubleshoot and repair the power supply. II. Troubleshooting Steps for Power Supply Issues 1. Check the Power Cable: Firstly, we need to inspect the power cable for any damage, such as breaks or poor connections. If a problem is found with the power cable, it needs to be replaced promptly. 2. Check the Power Connector: Secondly, we need to inspect the power connector for cleanliness and any dust or debris that may be blocking it. If there is any dirt or debris, use cleaning tools to remove it. 3. Listen for Sounds: When the computer is running, listen for the sound of the power supply fan. If you hear abnormal noise or the fan is not spinning, it may indicate a problem with the power supply fan or circuit board that requires further inspection and repair. 4. Use a Multimeter: If the above steps fail to resolve the issue, we can use a multimeter to test the voltage and current of the power supply. If abnormalities are found in voltage or current, it may be due to damaged internal components of the power supply that require replacement or repair. III. Repair Methods for Power Supply Issues 1. Replace Power Cable: If the power cable is damaged, replace it with a new one promptly. 2. Clean Connectors: If the power connector is blocked by dust or debris, use cleaning tools to remove it. 3. Replace Power Supply Fan: If there are abnormal noises or the fan does not spin, try replacing it with a new one. 4. Repair or Replace Internal Components: If internal components of the power supply are damaged, repairs or replacements need to be made according to the specific situation. IV. Preventive Measures

1. Regular Checks: Regularly inspect and maintain the computer's power supply to identify and resolve potential issues in a timely manner. 2. Use Quality Accessories: When purchasing computer accessories, choose high-quality products to reduce the incidence of power supply issues. 3. Pay Attention to Usage Environment: Avoid
