如果电源正常，但电脑仍无法启动，可能是电源接口问题。请检查电脑主机上的电源接口是否松动或损坏，如有需要可请专业人员维修。 3. 内部硬件故障 若排除电源和接口问题后，电脑仍无法正常工作，可能是内部硬件故障。此时，建议请专业人员检查并维修。可能的故障原因包括但不限于内存条、显卡、主板等硬件问题。 三、英文翻译 Power Connection and Troubleshooting Guide for Computers I. Power Connection with Computers 1. Power Cable Connection First, insert one end of the power cable into the power socket and the other end into the power interface of the computer host. Make sure the connection is secure to prevent poor contact that may cause the computer to fail to supply power normally. 2. Power Switch After connecting the power cable, press the power switch on the host, and the computer should start to boot. If the computer fails to start normally, please check whether the power switch is damaged or has poor contact. II. Troubleshooting 1. Power Supply Faults When the computer fails to start normally, the first step is to check whether the power supply is faulty. You can try connecting the power cable to other electrical equipment to determine whether the power supply is working properly. If there is a power supply fault, please replace it promptly. 2. Power Interface Issues If the power supply is normal but the computer still fails to start, it may be a power interface issue. Please check whether the power interface on the computer host is loose or damaged. If necessary, please ask a professional for repair.

3. Internal Hardware Failures If power and interface issues are ruled out, and the computer still fails to work normally, it may be due to internal hardware failures. At this point, it is recommended to ask a professional to inspect and repair. Possible causes of failure include, but are not limited to, memory sticks, graphics cards, motherboards, and other hardware issues.
