Windows computers are complex systems, and sometimes things go wrong: your PC may slow down, behave unpredictably, or display error messages. Diagnosing the cause doesn’t need to be intimidating, even if you’re new to Windows. With the right set of diagnostic utilities—some built-in, others third-party—you can troubleshoot most common issues yourself. This beginner’s guide will introduce you to essential Windows diagnostic tools, show you how to use them, and provide practical examples you can try right away.
What Are Windows Diagnostic Utilities and Why Do You Need Them?
Diagnostic utilities are tools designed to identify, analyze, and help fix problems in your Windows computer. Common issues include slow performance, hardware failures, software errors, and network problems. With basic knowledge and the right system tools, you can often resolve these problems without professional help.
Which Built-In Windows Tools Should Beginners Know About?
Windows offers several built-in utilities that are beginner-friendly and effective:
Task Manager
Task Manager is your go-to tool to check what’s running on your computer.
How to Use:
Press Ctrl + Shift + Esc to open Task Manager.
Check the Processes tab to see which apps use the most CPU, memory, or disk resources.
If your PC feels slow, look for any process using a high percentage of resources. Right-click and choose “End task” if it’s not a critical system process.
Windows Memory Diagnostic
This tool checks your computer’s RAM for issues.
How to Use:
Type “Windows Memory Diagnostic” in the Start menu and select it.
Choose “Restart now and check for problems.”
Your PC will restart and scan the memory. If errors are found, faulty RAM may be causing your problems.
Disk Check Utility (CHKDSK)
CHKDSK is used to scan your hard drive for errors and fix them.
How to Use:
Open File Explorer, right-click your main drive (C:), choose Properties.
Go to the Tools tab, under Error checking, click “Check.”
Follow the prompts. The tool will scan your drive and attempt repairs.
System File Checker (SFC)
Corrupted system files can lead to crashes and glitches. SFC scans and repairs these files.
How to Use:
Type “cmd” in the Start menu, right-click Command Prompt, and choose “Run as administrator.”
Type sfc /scannow and press Enter.
Let the scan finish. Follow any instructions if corrupted files are found.
Reliability Monitor
Reliability Monitor provides a timeline of system events and errors.
How to Use:
Type “Reliability Monitor” in the Start menu and select “View reliability history.”
Look for red X icons or warnings. Click them to see details about recent issues.

By running these checks regularly, you can catch many problems before they become serious.
What Should You Do After Diagnosing Issues?
If one of these utilities finds a problem, follow its recommended steps to fix it. Examples include:
If Task Manager shows a program using too much memory, try closing it or updating/reinstalling the application.
If Windows Memory Diagnostic finds errors, you may need to replace your RAM.
If Glary Utilities or CHKDSK reports disk errors, back up your important files and consider replacing your hard drive if issues persist.
If System File Checker finds and repairs files, restart your PC and see if the issue is resolved.
When Should You Seek Professional Help?
If diagnostic tools report repeated hardware errors (especially with RAM or the hard drive) or if Windows won’t start at all, it may be time to contact a professional. However, with the toolkit and steps above, you’ll feel more confident handling most everyday problems.
