Cleaning the motherboard with a dust brush and making sure it is dust free

2

Cleaning the power unit with anti-static foam cleaner by spraying the foam onto a separate surface and using a lint free cloth to clean the power unit.

By spraying onto the unit itself. It would damage the unit.

Cleaning the CPU by taking off old layers of paste simply using a duster or a lint free cloth to minimize the damage caused to the card.

Using the lint free cloth and spray to clean out the hard drive to prevent a build-up of dust and to keep the hard drive working correctly.

Using the brush to clean out the fan / cooling unit. I used the brush because the fans would easily break if using anything like an air compressor since it is to powerful and the parts can easily break.
