A technician opens up a PC to work on it, and finds that it is very dusty inside. What should the technician do?

  • Ignore the dust, as it does not affect the computer.
  • Use a lint-free cloth sprayed with a cleaning solution to remove excess dust.
  • Use a can of compressed air to remove excess dust.
  • Use a moistened cotton swab to remove excess dust.
    Explanation:

    Dust inside a PC can cause overheating, fan malfunction, and other problems. Liquid should not be used inside a PC to remove dust; compressed air will blow the dust away from where it has accumulated. Always hold the can upright and avoid dripping any of the fluid on the PC. Care should be taken to make sure that the compressed air does not blow materials back inside the case, and that fan blades are stabilized while using the compressed air.
