Check the power connections to the motherboard, ensure the power supply is functioning, and verify that the front panel connectors are correctly set. Also, test with minimal components to rule out hardware failures.
Enter the BIOS setup, navigate to the AI Tweaker section, and change the 'AI Overclock Tuner' setting to 'XMP'. Save and exit the BIOS to apply the changes.
