Computer tower cleaning- Physical dust cleaning

Cleaning a computer tower is quite a simple thing to do. You will need:

1. Phillips Head screw driver
2. Air duster can (small can of compressed air)
3. Clean paint brush of about 5cm wide

Firstly, turn off the computer, unplug all leads and take the computer tower outside.
Undo the two screws  holding the side of the computer furthest away from any rear plugs. These will be either phillips head screws or thumb screws.
Then, you will notice the motherboard and stuff inside your computer.

Some may look different to this older model, but the main fan that you can see here is the CPU fan, and is almost always in the same position in the case.
Take the paint brush  and gently push any dust away from the blades in the fans for the CPU and the case and power supply fans.
Then use the compressed air can to gently blow the dust bunnies from the computer.
Do not use an "air compressor" as the air blown from these devices can often be moist and too powerful.

After dusting simlpy replace the side of the computer and plug everything back in.
