Common Problems: 1. Startup issues: The computer cannot start normally, resulting in a black screen or blue screen. 2. Hardware malfunction: Components such as memory sticks and graphics cards cannot work properly, leading to decreased performance or inoperability of the computer. 3. Connection issues: Poor connection between the motherboard and other hardware devices, such as USB ports and hard drive interfaces. 4. Sound issues: Abnormal noises occur during computer operation. 5. Voltage issues: Unstable power supply voltage of the motherboard may cause the computer to malfunction. II. Solutions: 1. Startup issues: - Check if the power cord is properly plugged in and if the power supply is working normally. - Check if the display connection cable is loose or damaged. - Enter BIOS settings to check hardware self-diagnostics and look for possible error codes. - If the problem persists, it may be necessary to replace the motherboard or perform more detailed testing.

2. Hardware malfunction: - Re-plug hardware devices to ensure proper connection. - Use other hardware devices for replacement testing to determine the faulty device. - Ensure that any replacement hardware is compatible with the motherboard. - If the problem persists, it may be necessary to seek help from a professional repair technician. 3. Connection issues: - Check if all connection cables are properly plugged in and securely connected. - Try replacing the cables or ports to see if it resolves the issue. - If there is a problem with the USB port or hard drive interface, it may be necessary to replace the relevant components on the motherboard. 4. Sound issues: - Check if the fans are working normally and if there are any abnormal noises. - Inspect if there are any loose parts inside the computer, such as the hard drive. - If the sound comes from internal hardware, it may require more detailed testing and repair work to resolve the issue. (Here and below, some sections might not have direct English translation as they are more technical in nature.) 5. Voltage issues: 1) Examine power supply for normal operation and any voltage fluctuations. 2) Ensure that all power cables are properly connected and not damaged or aged. 3) If the problem persists, it may be necessary to replace the power supply or motherboard components involved in voltage regulation (In this case, more specific technical measures might be required, such as detailed hardware inspection and component replacement). Overall, addressing these common issues on a computer motherboard often requires a thorough understanding of hardware and potential for systematic testing to pinpoint the exact source of the problem. Seeking assistance from a qualified repair technician is always recommended to ensure effective troubleshooting and timely resolution of issues encountered with a computer’s motherboard.（关于
