This is an inside view of a computer that was pulled from a lab at Upper Valley Career Center. Older computers either go to auction, are recycled or are adopted out of inventory for use by the Computer Information Technology program for student use in hardware, software and operating system labs. The fuzzy, white stuff visible in the photo above is dirt. Not your typical brown, backyard type of dirt but more your particles blown in through ventilation system and kicked up from carpet type of dust/dirt. Computers pull "fresh" air in to help with cooling the chips on a motherboard and dust/dirt collects inside.
Students learn from technical sources that dirt is the number one enemy of computers. Dirt clogs vents, can gum up fans, and contribute to over-heating in computers. We have seen much worse than what is pictured above. If you have dogs, cats or live in the country with open windows your computer might look much worse than this. We have seen computers where you could pull out gobs of dirt. The owners wondered why their computers were over-heating or power supply's were burning out. Dirt. Dust. A need for cleaning and routine maintenance.
