There are many reasons you should routinely clean, as in literally sweep out and dust your computer.

There are a couple of really good reasons you should do this and they all have to do with heat. Heat is hard on electronics and when hair and dust collect on your computer’s internals, it essentially blankets your components and prevents heat from escaping.

Further, over time your system’s cooling fans become clogged and caked with dust, which compromises their effectiveness.

So, what you’re dealing with is a system that cannot quickly shed heat and thus ends up cooking itself. You can usually tell when you need to clean your computer by looking at the intakes and exhaust ports. Usually it’s as easy as glancing at the little holes that allow air to enter and exit. If those are covered or caked with dust, then it’s time to clean your computer.

You’ll have to shut down and unplug your computer before you begin, and then we recommend you take the entire unit outside. Once you start cleaning it out, all that dust and hair that has collected inside will need to be dislodged. You don’t want to introduce, or reintroduce all that into your house.

Canned air or vacuum?

While it may see easy to simply get out the vacuum cleaner and suck all that stuff out, don’t. Vacuum cleaners can discharge static electricity onto your computer’s delicate electronic components. We recommend canned air, to blast the dirt out.
