Some common beep codes that indicate a system board or power supply failure include:

• One long continuous beep tone: This usually indicates a problem with the power supply.
• Steady short beeps: This usually indicates a problem with the system board.
• No beeps: This usually indicates a problem with the power supply or the system board.
