Why is Dust BAD for Computers?

Dust is bad for your computer for two reasons:

1. Dust carries an electrical charge. Although it's a small charge, a buildup of dust means a buildup of electric. It takes only a small charge to destroy computers. You know when you walk across the carpet and then shock someone? That's too much for the computer! Buh bye Mr. CPU!
2. Dust acts as an insulator. That means it is keeping HEAT which is the enemy of computers in.

Never use a regular vacuum inside your computer! You can buy a specialized computer vacuum, but even I don't trust them too much. I used canned air. Don't use swifters! Again, that's an electrical hazard.  Never leave the slots or cover off the back of your computer because that draws dust in and doesn't allow the natural cooling system of the computer to work at top efficiency.
