- Confirm the front panel power button cable is correctly connected to the motherboard header.
- Fans Not Spinning:
- Check if fan cables are properly connected to the motherboard or fan controller.
- Ensure fan headers are enabled in BIOS/UEFI settings.
- No Display Output:
- Ensure your monitor cable is connected to the graphics card (not the motherboard, if a dedicated GPU is installed).
- Reseat the graphics card in its PCIe slot.
- Check graphics card power connections.
- Component Fit Issues:
- Refer to the specifications section for maximum component dimensions (e.g., GPU length, CPU cooler height, radiator size).
- Ensure all standoffs are correctly aligned for the motherboard.
