2. General Cleaning
Use a soft, dry cloth to clean the exterior surfaces and tempered glass panels. For internal cleaning, use compressed air to remove dust from components and fan blades. Always power off and unplug the PC before cleaning.
Troubleshooting
Common Issues and Solutions:
- No Power: Ensure all power cables (PSU, motherboard, components) are securely connected. Check the power supply switch.
- Overheating: Verify that all fans are spinning correctly and are oriented for proper airflow. Clean dust filters and internal components. Ensure liquid cooling systems are functioning.
- Components Not Fitting: Double-check component dimensions against case specifications (e.g., GPU length, CPU cooler height). Ensure proper installation angles.
- Front Panel I/O Not Working: Confirm that all front panel connectors (USB, audio, power/reset switches) are correctly plugged into the motherboard headers.
