Luckily, there are hundreds of diagnostic tools on the market to help you troubleshoot almost any problem you might be having with your Windows computer. We've rounded up five of the best diagnostic tools for your computer.
1. Windows Memory Diagnostic Tool
If you're not a fan of third-party applications, you're in luck. Windows' Memory Diagnostic Tool is built into the operating system, so you won't need to download anything extra.
What it does? It scans your RAM to see if it has any errors. Once it finds the error, it will tell you where it is so you can fix it. It's relatively simple to run:
- Hold down the Win + R keys to open the Run dialog box.
- Type mdsched.exe.
- Press Enter.
- The program will ask you to restart your computer now to check for problems. Make sure you save all your work before clicking this option.

2. WiFi Analyzer
Have you ever had an issue with slow internet? Slow Wi-Fi can cause problems, so if your Wi-Fi isn't meeting your expectations, try using our free Wi-Fi analyzer tool.
The tool analyzes your network to see if it's working effectively or if it needs to be tweaked in some way. Once it runs its diagnostics, it will tell you your best options for getting a better Wi-Fi signal.
3. Performance Monitor
No matter what version of Windows you have, it contains some form of Performance Monitor to ensure your computer is running smoothly. In Windows 10, it now exists as a separate app that comes with your computer.
Once launched, it shows how much of CPU was occupied when you opened the app, but you can add different widgets to give you more information, including energy consumed and disk usage.
Here's how to find it in Windows 10: Type Performance Monitor in the search box in the lower-left corner of Windows. Select the Performance Monitor app in the search results, and you're ready to use the tool.
