How do I keep my computer healthy?

Computers are expensive, and with all major purchases you probably want to protect your investment. Luckily, it is not difficult to keep your computer healthy and in good working order. Maintaining a computer involves three things: keeping it physically clean, protecting it from malware, and backing up important files.

Keep your computer physically clean 

When dealing with computers, dust isn't just unattractive—it can potentially destroy parts of your computer. By cleaning your computer regularly, you can help to keep it working properly and avoid expensive repairs.

Cleaning the keyboard 

A dirty keyboard doesn't look nice and can cause your keyboard to not work properly. Dust, food, liquid, and other particles can get stuck underneath the keys, which can prevent them from working properly. Check your owner's manual to see if the manufacturer has provided you with instructions for your specific keyboard. If so, follow them. If not, the following steps are basic cleaning tips that can help keep your keyboard clean.

Unplug the keyboard from the USB or PS/2 port. If the keyboard is plugged into the PS/2 port, you will need to shut down the computer before unplugging it.

Turn the keyboard upside down, and gently shake it to remove dirt and dust.

Use a can of compressed air to clean between the keys.

Moisten a cotton cloth or paper towel with rubbing alcohol, and use it to clean the tops of the keys. Do not pour alcohol or any other liquid directly onto the keys.

Reconnect the keyboard to the computer once it is dry. If you are connecting it to a PS/2 port, you will need to connect it before turning on the computer.
