However, due to various reasons, the motherboard may malfunction, resulting in abnormal computer operation. This article will detail how to troubleshoot and repair motherboard issues to help you solve common problems in computer operation. Common Signs of Motherboard Malfunction: 1. Computer fails to start or starts with difficulty. 2. System runs slowly or crashes frequently. 3. Hardware devices do not work properly (such as sound cards, graphics cards, etc.). 4. No signal from the display or abnormal display. 5. High temperature or loud fan noise, etc. Steps for Troubleshooting Motherboard Issues: 1. Visual inspection: Check if there is any obvious damage to the computer appearance, such as capacitor bursting, circuit board burning, etc. 2. Sound identification: Listen for any abnormal sounds during startup, such as warning beeps, to identify possible faulty components. 3. Plug-in and拔出 method: Try to plug in and out the main components such as memory sticks and graphics cards to see if the problem can be solved. 4. BIOS diagnosis: Enter BIOS settings to view system hardware self-test information and look for possible fault prompts. 5.
