A computer user logs a problem stating that the computer is emitting a loud clicking noise. Which device should the technician check first?

• hard drive
• CPU fan
• power supply
• motherboard
  

  Explanation: If a hard drive makes repeated clicking or tapping sounds when the computer is idle, the hard drive is failing. Make a backup and replace the drive as soon as possible. Invalid boot disk errors and files that suddenly will not open are symptoms of hard drive issues.
