It is necessary to approach computer problems from a logical standpoint. To best accomplish
this, PC technicians will implement a troubleshooting methodology (or
maybe more than one). CompTIA has included a six-step process within the 2009
A+ objectives. Memorize the steps listed in followings.


The Six-Step CompTIA A+ Troubleshooting Methodology
Step Description
Step 1 Identify the problem
Step 2 Establish a theory of probable cause (question the obvious)
Step 3 Test the theory to determine the cause
Step 4 Establish a plan of action to resolve the problem and implement the solution
Step 5 Verify full system functionality and, if applicable, implement preventative measures
Step 6 Document findings, actions, and outcomes


As you attempt to troubleshoot computer issues, think in terms of this six-step
process. Plug the problem directly into these steps. If you test a theory in Step 3,
and the theory is disproved, return to Step 2 and develop another theory. Continue
in this manner until you have found a theory that is plausible.
