- Check that the front panel power switch cable is correctly connected to the motherboard header.
- Fans Not Spinning/Lighting:
- Ensure the Molex connectors for the pre-installed fans are securely connected to the PSU.
- Check if the light switch button on the front I/O panel is activated.
- Front Panel USB/Audio Not Working:
- Verify that the USB 3.0, USB 1.0, and HD Audio cables from the front panel are correctly connected to their respective headers on the motherboard.
