Chapter 9: Optimizing PC Performance and Preventative Maintenance

Labs you will perform in this chapter:

• Lab 9.1: Cleaning Computer Components

Most of us hate doing housework. Yet one of the easiest ways to ensure that our computers stay at peak performance is to do a bit of regular cleaning inside the case. Dust and dirt act as insulators. The buildup of dust inside the computer prevents the system from cooling properly. This situation definitely affects performance and the longevity of the components.
