Finally, don't worry about damaging the computer. Unless you do something really stupid-such as throwing a glass of Coke into the computer while it's running-you won't hurt your PC. The only component that you could conceivably damage-if you don't count chips zapped by the homicidal static electricity-is the hard drive. The platters inside it are spinning at a breathtaking rate within fractions of a millimeter from other parts that could, if jostled, collide like race cars on Memorial Day. But don't worry. This is going to be a midnight run.
What are they talking about? What is a midnight run?
