Determine if the Problems Hardware Related or Software Related
This step is important because it determines what part of the computer you should focus your troubleshooting skills on.Each part requires different skills and different tools.
To determine if a problem is hardware or software related,you can do a few things to narrow down the issue.For instance,does the problem manifest itself when you use a particular piece of hardware(a modem, for example)? If it does, the problem is more than likely hardware related.
This step relies on personal experience more than any of the other steps do.you will without a doubt run into strange software problems.Each one has a particular solution.Some may even require reinstallation of the software or the entire operating system.
