Williams Sundial Properties: a Computer Handbook!

I have a history with the purchasing, upgrading, and repairing of personal computers, and they make your life easier when they are working fine, however, they can become expensive door stops when they crash! The more you learn about the operation of your own personal computer and how to install software and hardware and upgrade the software and hardware systems, on your own, the more money you will save. Personal Computers can become very expensive if every time the computer freezes up, crashes, or fail to come on, you must call an Electronic Technician, or Computer Technician to restore it to operations.
