Surprisingly, one little known fact is that the paper you use in your printer absorbs moisture, just like a sponge. Especially during the summer months when humidity levels are high. The properties of the material used to make paper have a strong attraction for water. This can greatly effect print quality that most people blame on the printer itself. If you have a laser printer and the paper has too much moisture content, you will see “smoke” coming out of the top of the printer.
Heat is the eternal enemy of computers and the number one reason your desktop, tower or laptop may be overheating is that the airflow designed to cool your PC has been disrupted or even blocked by dust and particles like hair (human & pet), skin cells, bugs and pollen that get sucked into your expensive PC by their fans.
A computer virus is a computer program that is hidden in another seemingly meaningless program that produces copies of itself and inserts them into other programs or files, and usually performs a malicious action (such as destroying data). Once created and released, it can unknowingly take over your computer without your knowledge.
