Things you will need:

  • Screwdriver
  • Small brush with soft bristles (e.g., a baby toothbrush or a make-up powder brush.) ONLY USE THIS FOR YOUR PC.
  • Thermal paste for your CPU. This should only be used if there are little to no paste visible on the CPU or if it’s crusty


*NB! *


  • Firstly, you will have to turn off your computer. Unplug your computer and hold the power button for at least 15 seconds to allow the remaining power to run out.
  • Remove all the accessories and cables that are plugged in externally (Keyboard, Mouse, VGA, etc.)
  • Open your PC and as a tip you should take a picture of how it looks to guide you on where to put everything once you’re done.
  • Remove your PSU, RAM, Graphics card (if you have one inserted), Hard Drives or Solid-State Drives, Fans (such as the CPU and Cooling Fans), CPU (remember only remove the CPU if the thermal paste is old or dried up).
  • Remove your power supply and eventually your motherboard. Place all those parts in a safe spot, as well as all the screws.
  • Next, clean the inside of your computer box with a soft bristle brush of your choice. Use this brush to clean your hardware parts too. Be as gentle as you can while make sure that there are no Dust Bunnies lingering around.
  • Once you see that all the dust is cleared, begin the reassembling of your computer. (Remember to use the picture you took for guidance)
  • Firmly fit your motherboard into the box. We don’t want to have it all wobbly now. Do we?

  • Also make sure all screws are accounted for when required.
  • *You can skip this step if you didn’t remove the CPU (It’s the Central Processing Unit or the computers brain if you’re still wondering). If you need to reapply thermal paste to the CPU you may but handle it with care. Spread the paste out evenly and put the CPU back into its socket. Be careful around the pins, they break easily.
  • Once all the parts are back in place, close your PC and start her up.
