17. Steps in the Troubleshooting Process

18. Verify Obvious Issues
The first step in basic troubleshooting process is to check
the simple or obvious issues first. Start with the obvious
issues before moving to more complex diagnose.
Here is a list of obvious issues to check:
Loose external cable connections
Incorrect boot order in BIOS
Non-bootable disk in floppy drive
Power switch for an outlet is turned off
Device is powered off

19. If the problem is not resolved when you verify the obvious
issues, you will need to continue with the troubleshooting
process.
If you find an obvious issue that fixes the problem, you
can go to the last step.

20. Try Quick Solutions
The next step in the troubleshooting process is to try quick
solutions first. Obvious issues and quick solutions sometimes
overlap each other and can be used together to repair a problem.
• Restart the computer.
• Re-seat cables
• Cycle the power.
If a quick solution does not resolve the problem, document your
results and try the next most likely solution.
