7. Troubleshooting
If you encounter issues with your PC build, consider the following general troubleshooting steps:
- No Power: Double-check all power connections from the PSU to the motherboard, CPU, and GPU. Ensure the PSU switch is in the 'ON' position.
- No Display: Verify that your monitor is connected to the graphics card (not the motherboard's integrated graphics ports, unless you are using integrated graphics). Reseat the graphics card and RAM modules.
- Overheating: Ensure all case fans and CPU cooler fans are spinning correctly. Check for dust buildup on filters and heatsinks. Verify proper thermal paste application on the CPU.
- Component Fit Issues: Refer to the specifications section to ensure all components (GPU, CPU cooler) are within the case's maximum supported dimensions.
