3. Startup Test: Attempt to start the computer in different modes to determine if the issue is with the operating system or hardware. 4. Hardware Diagnostics: Use BIOS or specialized hardware diagnostic tools to check the status of the motherboard and various hardware components. **Repair Methods for Motherboard Issues** 1. Cleaning and Re-seating: Clean dust and debris from the motherboard and re-seat all hardware connections to ensure proper connection. 2. BIOS Update: If the BIOS version on the motherboard is outdated, it may cause system instability or prevent recognition of new hardware. Consider updating the BIOS to the latest version. 3. Substitution Method: Replace potential faulty hardware components one by one, such as memory sticks or graphics cards, to determine the source of the problem. If the issue is resolved after replacement, it indicates a problem with that specific hardware component. 4. Professional Repair: If none of the above methods resolve the issue, it may be necessary to take the motherboard to a professional repair service for further inspection and repair. **Prevention Measures** 1. Regular Cleaning: Regularly clean the interior of the computer to remove dust and debris and keep hardware in a clean state. 2. Moisture and Dust Protection: Maintain a suitable humidity level around the computer and avoid placing it in dusty environments. 3. Regular Maintenance: Perform regular hardware maintenance and check for potential issues. 4. Use Genuine Products: Purchase computers and accessories from legitimate channels and avoid using counterfeit products. 遵行以上建议和方法，我们能够有效地解决和
