What is the CompTIA Troubleshooting Theory? The theory consists of six systematic steps that you follow to effectively identify a computer problem. It is important that you stick to the steps in the order as listed.
By following these steps you eliminate jumping around and wasting hours on a problem. You may find that once you have exhausted all avenues, to the best of your abilities (and knowledge), that it is time to take the problem to another person (or higher technical level) for possible resolution.
It is best practices to always maintain a document trail of your findings so that in the future you are better prepared to effectively deal with future problems.
The six CompTIA Troubleshooting (Theory) Steps are:
- Identify the problem – Question the user and identify user changes to computer and perform backups before making changes.
- Establish a theory of probable cause – Question the obvious.
- Test the theory to determine cause – Once the theory is confirmed, determine the next steps to resolve problem. If the theory is not confirmed, establish a new theory or escalate.
- Act – Establish a plan of action to resolve the problem and implement the solution.
- Test and prevent – Verify full system functionality and, if applicable, implement preventative measures.
- Report – Document findings, actions, and outcomes.

Just when I think I have found most of the golden nuggets on the internet, I come across another. While performing an update to the Bookmarks4Techs listing, a visitor to the site contacted me and suggested that I add the tech site GEGeek – PC Tech Quick Reference to the listing.
What I expected to find was a tech blog, but what I came across is a Geek’s paradise for anyone who is into computers; and especially, computer repair & troubleshooting. While you are there, pay special attention to the GEGeek Tech Toolkit. This toolkit should be called a Tech Tool Shop… It is a 1.0 gig download and contains everything, as a tech, you would ever need.
An excerpt about the author of GEGeek:
This site is the culmination of years of CAREFULLY selecting a handful of links to assist me on my current job, personal consulting work and of course my own PCs. Not every site has all useful links ⁄ articles, but there were always one or two gems to be found on every site I visited. Keeping them readily available and manageable became quite a chore, so i created this site just to help me organize them and provide a quick reference . The “How To” is assumed knowledge, I just provide the quick reference.
