Does your computer look like this?
The accumulation of dust, hair, and other particulates inside your computer is inevitable.  This is due to the cooling fans located inside.  It is not a reflection of your housekeeping but must be addressed and cleaned.  As the pictures above portray, these particulates can build up over time.  These pictures are characteristic of extreme neglect.  Most users do not even realize that this is a maintenance issue.  Some people do know that the system needs to be cleaned but try to do it with vacuum cleaners or compressed air.  That sounds like a good idea but, in reality, you are chancing serious damage because air, rushing across the boards causes static electricity.  This static electricity can and HAS shorted out motherboards, CPUs, and any number of other components.
