1. 电源不工作： - 检查电源线是否插好，确保电源插座正常工作。 - 检查电脑主机内部的电源连接线是否松动或损坏。 - 如果以上都正常，可能是电源本身的问题，需要更换新的电源。 2. 电源过热： - 清理电源内部的灰尘，提高散热效果。 - 确保电源风扇正常运转，如有故障需及时更换。 - 避免长时间高负荷运行，给电脑适当的休息时间。 3. 噪音过大： - 更换新的电源风扇，或给现有风扇加油润滑。 - 检查风扇是否因为安装不当造成噪音，重新安装固定。 4. 电压不稳定： - 检查电源线是否老化或损坏，如有需要更换新的电源线。 - 使用稳压器或UPS设备来稳定电压。 - 如果问题依旧存在，考虑更换新的电源。 5. 无法满足高负荷运行： - 检查电脑其他硬件配置是否足够支持高负荷运行，如显卡、内存等。 - 如果硬件配置足够，但仍然出现此问题，可能需要更换功率更高的电源。 - 在高负荷运行时，可以适当降低系统负载，如关闭一些不必要的应用程序和后台任务。 三、翻译成英文： **Common Issues and Solutions for Computer Power Supplies** I. Common Issues: 1. Power Supply Not Working: The computer shows no response when the power button is pressed, and the power indicator does not light up. 2. Overheating of Power Supply: During use, the computer power supply becomes excessively hot, which may cause system instability or automatic shutdown. 3. Excessive Noise: The power supply fan produces a loud noise when operating, affecting the user experience. 4. Voltage Instability: The output voltage of the power supply is unstable, which may damage the internal hardware of the computer. 5. Inability to Meet High-Load Operation: Under high-load conditions, such as playing demanding games or running high-performance software, the power supply cannot provide sufficient power support. II.

1. Power Supply Not Working: - Check if the power cord is properly plugged in and ensure the power socket is working normally. - Check if the power connection inside the computer case is loose or damaged. - If everything is normal, it may be a problem with the power supply itself, and a new one needs to be replaced. 2. Overheating of Power Supply: - Clean the dust inside the power supply to improve cooling efficiency. - Ensure that the power supply fan is operating normally; if there is a fault, replace it promptly. - Avoid prolonged high-load operation and give the computer adequate rest time. 3. Excessive Noise: - Replace the power supply fan or lubricate the existing fan. - Check if the fan is making excessive noise due to improper installation and re-install it securely. 4. Voltage Instability: - Check if the power cord is aged or damaged and replace it if necessary. - Use a voltage stabilizer or UPS device to stabilize the voltage. - If the problem persists, consider replacing the power supply with a new one. 5. Inability to Meet High-Load Operation: - Check if the other hardware configurations of the computer, such as the graphics card and memory, are sufficient to support high-load operation. - If the hardware configuration is sufficient but the problem still exists, you may need to replace the power supply with a higher wattage model. - During high-load operation, you can reduce system load by closing unnecessary applications and background tasks.
