CSIP Level 1 Troubleshooting: All Troubleshooting Starts Here
Checking for Obvious Causes
Check for the following obvious causes:
• Check for correct voltage at electrical outlets, “tripped” circuit breakers, blown fuses, and
disconnected or damaged wires. Always check that power cords are plugged in, and inspect
them for wear.
• Consider the situation: Was there a system option or hardware change recently? When was
the last time the system was working correctly and what, if any, influencing circumstances
have occurred since?
• Check if the symptom and probable cause may already be documented.
Investigating and Testing
If you haven’t discovered the cause of the problem yet, more in-depth analysis is necessary:
• Take a moment to review the data you’ve collected about the problem so far. Hopefully, you
have been able to categorize the symptom as a hardware, software, operator-induced, or
environmental failure.
- Hardware failure: Cause usually determined through use of troubleshooting tools (RST,
Device Manager, Debug Info, and Event Logs). A fix is typically realized by replacing sus-
pect/candidate hardware until the problem is resolved.
NOTE Consider the value against the difficulties of swapping (suspect) hardware components
with good ones. Do not cause additional problems or confuse your search. Never swap
parts if a known good item might be damaged.
