Establish a theory of probable cause.
The CompTIA troubleshooting methodology follows a strict order: 1) Identify the problem, 2) Establish a theory of probable cause, 3) Test the theory, 4) Establish a plan of action and implement the solution, 5) Verify full system functionality and implement preventive measures, and 6) Document findings. Since the technician has already gathered information and reproduced the issue (Step 1), the immediate next step is to establish a theory of probable cause.
