Computer Maintenance is a pre-requisite if you want to keep your system running in tip top condition.
Just like your car (which I’m sure you wouldn’t neglect to service for years) a regular computer service is vital for your system as well.
Another factor that is often overlooked when it comes to computer maintenance is the need for computer cleaning. A well built system will have at least one internal fan (and sometimes more) to suck fresh air into the system to keep it running nice and cool.
A problem with this is that no matter how clean you keep your house or office the computer sucks in copious amounts of dust. Over a very short period of time this dust starts to clump and clog up your vital components.
This in turn will cause the components to overheat thereby degrading your system performance and in the worst cases your computer can completely overheat and fry the most expensive parts forcing an unplanned computer upgrade, sometimes to the point of making it uneconomical to repair
