Four Easy Diagnostic Tricks That Can Save Your Computer

Most of your homework is done with the help of your computer. You google information for your projects. You do your written assignments using Word, Pages, or Google Docs. During the COVID-19 pandemic, students managed to continue their education thanks to computers and the internet. All in all, we are extremely dependent on computers. 

And now imagine a situation in which you are doing an assignment, and suddenly your computer crashes. Or your computer runs so slow that working on it makes you desperate. In cases like that, working on your essay is the last thing that you want to do. You need to figure out other ways to do your assignment. 

Of course, you can call professional help and use a computer at your college’s library while your PC is being fixed. Another option is to order your paper using a ‘write my essay online’ service to get more time to focus on fixing your PC. But professional help aside, what can you do personally? Hopefully, there are several things that you can do to save your computer. 

First, when having some problems with your computer, you can run diagnostics. But we face one problem here: are you using a Windows PC or Mac? They require different approaches. Let’s start with Mac, as it’s simpler than Windows PC. 

Running Diagnostics on Mac

Whenever you notice something is wrong with your Mac and suspect that the reason lies in hardware components, you can use Apple Diagnostics. It’s a built-in test system that detects what hardware parts are causing the problem. Using Apple Diagnostics, you can check the power controller, logic board, battery, RAM, and wireless modules. 

Even if it sounds difficult and time-consuming, the process is unlikely to take longer than five minutes. Five minutes for what you might have wasted several hours. But before you run the diagnostics, you need to prepare your Mac for it. Take the following steps:

  • disconnect all external devices unrelated to Mac;
  • make sure that you have a solid Internet connection;
  • make sure that your Mac is on a stable surface.

Now, after you’ve finished preparing your Mac, go to the Apple Menu and select Restart. Then, press and hold the “D” key until the list of different languages appears. Select your language, and Apple Diagnostics will start automatically. Now, you need to give it between two and five minutes till the process is complete. 

When Apple Diagnostics is finished, you will know the problem’s cause. Aside from that, you will get several ways of fixing the problem. A great thing is that Apple Diagnostics provides you with the error code as well. If you fail to fix the problem on your own, you can always contact Apple Support, so they can offer you the solution based on the code. 

Running Diagnostics on Windows PC

Running diagnostic tools on Windows is also quite easy, but you may find it difficult to find what’s what from time to time. Windows, just like Mac, allows you to find the problem with your computer when you struggle to figure out what is wrong. So, let’s check what tools Windows PCs have in store for their users. 


If you can’t pinpoint the reason behind your computer’s lagging, the best option is to troubleshoot. So, in case you are using Windows 10, go to Settings, choose Update & Security section, and select Troubleshoot. If you are using Windows 11, go to Start, choose Settings, select the System section, and click Troubleshoot. 

After hitting Troubleshoot, you need to select the area you’re having problems with. The Troubleshoot list includes everything from issues with power and network adapter to the keyboard and Bluetooth. If the program finds the problem, it will suggest several solutions for fixing it. Often, you can fix the issue by automatically repairing Windows. 

Memory Diagnostics


Working on a computer turns into living hell if programs keep lagging or freezing. You try googling something, but it takes ages for the page to load. You need to open a folder, but it takes a minute for it to do so. While you are waiting, you might click on the folder repeatedly and have the same folder opened several times as a result.

Well, it can be a sure sign that you have a problem with your RAM. The best option here would be to run the Windows Memory Diagnostic Tool. Open Windows Search and type “Memory Diagnostic.” Then, select the app to open it. You will be given two options for diagnostics:

  • restart now and check for problems;
  • check for problems the next time I restart.

Depending on how dire the situation is, you choose one of the options. If you opt for the first one, the computer will restart, and the tool will begin scanning your computer for the problems. If you opt for the second one, the program will start the scan the next time you restart your computer. 

After the scan is completed, your PC will boot as normal. Then, you need to go to the Event Viewer to check the results of the scan. If the Memory Diagnostic Tool has found the problem, you can opt for freeing up memory on your computer. 

Reliability and Performance Monitors

Another option is checking Windows Reliability and Performance Monitors. Those are built-in administrative tools. You can find and open them using Windows Search. Thanks to those tools, you can check out the statistics of your computer. If it’s acting funny, check the monitors to see which of the programs on your PC are acting up. 

Final Thoughts

Of course, there are third-party programs that you can install to keep your computer safe. Some programs allow a deeper scan or clean out the trash from your computer automatically. They come in handy and have affordable prices. Still, the built-in tools allow you to find the problem without installing something new on your computer.
