Clean a Desktop PC Motherboard

As your computer ages, dust will build up inside of it. The intake fans suck dust in and then it collects near the vents and on the motherboard.If not removed from time to time dust can cause your computer to overheat and malfunction. It can even short circuit and ruin your motherboard!

Steps

  1. Turn off and unplug your computer.
  2. Use compressed air to remove dust.
    • Purchase a can of compressed air ( can be found on line and at most department stores) Or alternatively you can use an air compressor. But make sure to have your PSI setting below 50 PSI to ensure you do not damage your motherboard.
  3. A soft tipped paint brush will work as well for dust that has caked up in areas such as the fans, power supply, intake vents and between RAM modules.
  4. Open your computer's case. The case may be held together with screws or some other mechanical latching system.
    • If you cannot figure out how to open your case, consult your manual for your PC or Google you computers model number for details.
  5. Blow all parts of the motherboard, including the fan and the heat sink.
  6. Close the computer's case.
  7. Plug in the computer, and turn it on.



Tips

  • Some fans will only spin if you attempt to clean them using compressed air. Try using a Q-Tip or other object to remove dust.
  • Compressed air works great for cleaning your keyboard as well

Warnings

  • Make sure to eliminate all static electricity. This can be done by touching the metal chassis of your computer or using a commercially bought electrostatic discharging wrist strap. (these can be found on line, or at electronics stores)
  • Do not Exceed 50 PSI when using an air compressor if the dust isn't coming off at this pressure rating, use a soft bristled brush to remove the dust.
  • Do not attempt to open a power supply to clean it

Things You'll Need

  • Can of compressed air
