4.2. General Cleaning and Care
Regularly clean your motherboard and PC components to prevent dust buildup, which can lead to overheating and performance issues. Use compressed air to remove dust from fans, heatsinks, and other components. Ensure the system is powered off and unplugged before cleaning.
5. Troubleshooting
If you encounter issues, refer to the following basic troubleshooting steps:
- No Power: Ensure all power cables (24-pin ATX, 8-pin CPU, 4-pin CPU) are securely connected to the motherboard and power supply. Check the power supply unit (PSU) switch.
- No Display: Verify that the graphics card is properly seated in its PCIe slot and any necessary power cables are connected. Ensure your monitor is connected to the graphics card (or motherboard if using integrated graphics) and is powered on. Try reseating RAM modules.
- System Instability/Crashes: Check for proper CPU and GPU cooling. Ensure RAM modules are correctly installed. Update BIOS and drivers to the latest versions.
- Component Not Detected: Verify that the component (e.g., M.2 SSD, SATA drive, USB device) is correctly installed and connected. Check BIOS settings to ensure the port is enabled.
