In this tutorial, we learn how to clean dust & dirt from your desktop computer. First, take the front panel off of the tower and then clean the area around the fan off as well. Use a vacuum cleaner to suck the dirt out but make sure not to touch the surface on the system. On the inside you can use cotton swabs and wash cloths that are slightly damp. You can also use a small straw and remove the dirt and dust from the fan and the areas around it. When finished, your computer should be running faster and more efficiently than before!
