Many operating systems have built-in diagnostic tools that can help identify and resolve specific issues. Explore your OS settings for these tools.

Check event viewer

On Windows, use the Event Viewer to review system logs for any error or warning messages that can provide clues about the problem.

Test in another user account

Create a new user account and see if the issue persists. This can help determine if the problem is user-specific or system-wide.

Ask for help

If you’ve exhausted your troubleshooting options or are unsure about potential solutions, don’t hesitate to seek help from online communities, forums, or tech-savvy friends.

Working with a company specialising in IT solutions can help you solve problems more quickly. If you are uncomfortable or unsure about a particular troubleshooting step, it’s best to seek professional assistance to avoid causing further damage.

The use of the process of elimination

If finding the cause of a problem becomes a challenging task, using the process of elimination can help reach the root of the issue and find a more efficient solution.

The process is a systematic troubleshooting technique used to narrow down the possible causes one by one until the true cause is found. The method is especially useful when there are multiple variables or components that could be responsible for the problem.

Here’s how it works:

Identify the problem

Begin by clearly defining the problem or symptoms you are experiencing. Understanding the exact issue is crucial to start the elimination process effectively.

Create a list of potential causes

Based on your knowledge and experience, list all possible factors that could be causing the problem. This list should include both common and less likely causes.

Organise the list by probability

Arrange the potential causes in the order of likelihood. Start with the most common and easily verifiable causes at the top of the list.

Test and eliminate

Begin testing each potential cause one by one. Start with the most probable cause and work your way down the list. For each test, observe the behaviour of the system and note any changes.

Document the results

Keep a record of the steps you take, the results of each test, and any relevant observations. This documentation will help you keep track of your progress and can be useful for future reference.

Repeat the process

If a test does not reveal the root cause, move on to the next potential cause on the list. Continue the process of elimination until you find the cause of the problem.

Verify the solution

Once you identify the likely cause, perform further testing or verification to confirm that it is indeed the root cause. Sometimes, there might be multiple factors contributing to the problem.

Implement the solution

After identifying the root cause, apply the appropriate fix or solution to resolve the issue.

Test the system

Finally, test the system again to ensure that the problem has been resolved and that no new issues have been introduced.

How to solve more difficult problems

We have explained how you can deal with simple problems and find common solutions. However, that is not always the case. Sometimes you’ll find more challenging issues that require more complex strategies, combining technical knowledge, critical thinking and perseverance.

Here are some strategies to help you tackle these issues:

Research and gather information

Start by thoroughly researching the problem. Use search engines, online forums, official documentation, and technical resources to gather information about the issue. The more you understand the problem, the better equipped you’ll be to solve it.

Break down the problem

Complex issues can seem overwhelming. Break the problem down into smaller, manageable components. Identify the symptoms and potential causes for each component.

Prioritise and focus

Determine which parts of the problem need immediate attention and focus on those first. Addressing critical issues can often lead to resolving other related problems.

Consult expert resources

Don’t hesitate to seek help from experienced professionals or technical communities. Online forums, community groups, or even contacting official support channels can provide valuable insights and solutions.

Test and validate assumptions

Formulate hypotheses about the root cause of the problem and systematically test them. Verify your assumptions through testing, and use the results to guide your next steps.

Keep detailed records

Document all the steps you take, including changes made and results observed. Having a record of your troubleshooting process can be helpful if you need to retrace your steps or seek assistance.

Try different approaches

If a particular solution doesn’t work, try alternative methods. Be open to different approaches and explore creative solutions.

Be cautious with system changes

Avoid making too many changes simultaneously, as this can make it difficult to determine which change caused the problem or if any changes conflict with one another. Make one change at a time and retest.

Use diagnostic tools and logs

Many operating systems and software applications have built-in diagnostic tools and log files that can provide valuable information about errors and system behaviour. Utilise these tools to aid your troubleshooting.

Patience and persistence

Complex problems may not have quick solutions. Stay patient and persistent in your efforts, and remember that solving challenging issues can take time.

Backup important data

Before attempting any major changes or fixes, back up critical data to prevent data loss in case something goes wrong.

Stay update

Keep your operating system, drivers, and software up-to-date. Sometimes, updates can resolve known issues or provide new features and optimisations.

Consider systemic factors

In some cases, problems may be caused by larger systemic issues, such as hardware compatibility, network configuration, or environmental factors. Think broadly about all potential influences on the problem.

Take breaks

If you’re feeling stuck or overwhelmed, take a short break to clear your mind. A fresh perspective can sometimes lead to breakthroughs.
