- Verify all power cables (24-pin ATX, 8-pin CPU, PCIe power) are securely connected to the motherboard and components.
- Check that the front panel power button cable is correctly connected to the motherboard's front panel header.
- Fans Not Spinning / RGB Not Working:
- Confirm that the fans are properly connected to the motherboard or the integrated RGB hub.
- Ensure the RGB hub is receiving power and is connected to the motherboard's RGB header (if applicable).
- Check your motherboard's BIOS/UEFI settings or RGB software for fan control and lighting options.
- USB Ports Not Functioning:
- Verify that the USB 3.0 and USB Type-C cables from the front panel are correctly connected to the corresponding headers on your motherboard.
- Check your motherboard's drivers and BIOS settings.
- No Display Output:
- Ensure your monitor cable is connected to the graphics card (GPU) output, not the motherboard's integrated graphics ports (unless you are using integrated graphics).
- Reseat the graphics card in its PCIe slot.
- Check that the GPU is receiving adequate power from the PSU.
