Find the case release lever on your computer's case. If your Pentium 3 computer is designed to sit flat on a desk, the case release lever should be located on the top of the computer. If you have a tower design computer the case release lever should be located on the side. Pull the case release lever, remove the case cover and set it aside.

Look inside the computer's case for accumulated fuzz, dust and dirt. Over time dust and dirt from the room can make their way into the computer, and this dust and dirt will block the airflow the computer needs to cool itself off.

Take out your can of compressed air and attach the straw that came with the can. Give the can a couple of quick test sprays--this will remove any moisture that may have accumulated inside the can. Use the compressed air to spray out the inside of the computer.

Pay particular attention to the area around the power supply. The fan attached to the power supply will often draw dust and debris into the computer, so you could have a significant accumulation of dust and dirt there. After all of the dust and dirt has been removed from the inside of the case, reassemble the computer and turn it back on.
