One way to tackle a problem is through substitution-a tactic that can be just as valuable in the computer worlds as it is on the football field. It involves substituting a device that you know is working for one that's suspect.
Here's how that works: Let's say your monitor is flickering. Maybe the problem is in the minitor, but it also could be the video card. You can't decide what to replace until you know where the problem lies.
Many of us have more than one computer these days. So taking a working monitor from another computer and replacing the flickering one will narrow the diagnosis. If the problem stops, you know you need a new monitor. If the flickering continues, it's clear the problem may be the video card.
The same technique will help you diagnose a balky mouse, a suspect keyboard or a cable that my be going bad.
