Understanding how your Windows computer works and learning to diagnose issues is an essential skill for all users. Fortunately, Windows comes with built-in diagnostic utilities that are user-friendly, powerful, and designed to help you pinpoint and fix common problems. This guide is tailored for beginners, focusing on easy-to-use tools and practical steps you can take to keep your system running smoothly.
What Are Windows Diagnostic Utilities?
Windows diagnostic utilities are special tools included with the operating system that help you check the health of your hardware, monitor system performance, and troubleshoot errors. These built-in features require no extra downloads and are safe to use. Some tools help you monitor your computer’s resources, while others actively scan for or repair issues.
Which Built-in Tools Can Help Diagnose My System?
Here are some of the most useful diagnostic utilities available in Windows:
1. Task Manager
2. Performance Monitor
3. Windows Memory Diagnostic
4. Check Disk Utility (CHKDSK)
5. Reliability Monitor
6. Windows Troubleshooters
How Do I Use Task Manager to Diagnose My Computer?
Task Manager is your gateway to understanding what’s happening on your PC in real-time. Here’s how to use it:
– Right-click on the taskbar and select Task Manager, or press Ctrl + Shift + Esc.
– On the Processes tab, you can see which apps and background processes are using the most CPU, memory, disk, and network resources.
– If your computer is slow, look for any programs using excessive resources. You can close them by selecting the program and clicking End Task.
Real-world example: If your browser is frozen and using up a lot of memory, use Task Manager to close it and restore performance.
What Is Performance Monitor and How Can I Use It?
Performance Monitor provides in-depth information about how your system is running over time.
– Press the Windows key, type Performance Monitor, and open it.
– Click on Performance Monitor under Monitoring Tools.
– Here, you can add counters like CPU, memory, disk, and network usage.
Tip: For beginners, focus on watching trends like CPU or disk spikes. If you see constant high usage, it could point to a background process or malfunctioning app.
How Do I Check My Computer’s Memory for Problems?
Faulty RAM can cause crashes and blue screens. Windows Memory Diagnostic makes checking your memory easy:
– Press the Windows key, type Windows Memory Diagnostic, and press Enter.
– Choose Restart now and check for problems.

If errors are found, you may need to replace your RAM.
How Can I Scan for and Fix Disk Errors with CHKDSK?
Hard drive errors can slow down your computer or cause data loss. Use the Check Disk Utility as follows:
– Open File Explorer, right-click your system drive (usually C:), and select Properties.

This tool is helpful in identifying patterns, such as frequent application crashes or hardware issues.
How Do Windows Troubleshooters Simplify Problem Solving?
Windows includes built-in troubleshooters for common problems like internet connectivity, audio, and printers.

– Click on the area you’re having trouble with, then Run the troubleshooter.
Windows will automatically check for problems and suggest fixes.
