Solution: a. Check if the power supply fan is working properly, and replace it if not. b. Clean the dust inside the power supply and ensure good ventilation. c. If the above steps fail to solve the problem, it may be necessary to replace the power supply with a new one. 2. Insufficient Power Supply: Problem Description: The computer experiences power shortages during operation, such as automatic shutdowns or restarts. Solution: a. Check if the power supply has enough power to meet the hardware requirements of the computer. b. Check if the power cord is properly plugged in and damaged. c. If using an old power supply, it may be necessary to replace it with a new one with higher power capacity. 3. Non-functional Power Supply: Problem Description: The power supply completely does not work, and there is no response from the computer when the power is connected. Solution: a. Check if the power cord is properly plugged in and damaged. b. Check if the power switch is normal, as sometimes it may be damaged causing the power supply to fail to start. 4. Overheating of Power Supply: Problem Description: The computer power supply runs at an excessively high temperature, which may cause damage or malfunction of the power supply unit (PSU). Solution: a. Ensure that the power supply has sufficient ventilation space and avoid a crowded hardware environment. b. Clean the dust from the power supply fan and cooling fins to maintain good cooling efficiency. c. If the power supply is already aged or damaged, it may be necessary to replace it with a new one.
