You can start cleaning with compressed air by first turning off the computer and unplugging it from its power supply. Disconnect any equipment that is attached to the computer.

The next step would be to remove the computer case and ground yourself, to prevent any shocks or sparks.

Compressed air can be sprayed towards the areas with noticeable dust on them, being careful not to touch or disengage any connections.

A soft cloth can be used to wipe out the inside of the computer, as long as care is taken to work around the connections.

Afterwards, close the computer's case again, reconnect the equipment that was attached to it, turn on the electrical supply, and boot up your computer.

It is best to select a LCD monitor with a latency of eight milliseconds or less.
