Running hardware diagnostics on Windows 10 might sound daunting, but it’s simpler than you think. With just a few steps, you can identify and troubleshoot any hardware issues your computer may have. Here’s how to do it: Use built-in tools like the Windows Memory Diagnostic and Device Manager, or third-party software, to ensure all your hardware components are working correctly. Let’s get started!
How to Run Hardware Diagnostics on Windows 10
Running hardware diagnostics on Windows 10 is essential for keeping your computer in top shape. Here’s a step-by-step guide to help you identify and fix hardware issues.
Step 1: Open the Control Panel
Open the Control Panel by typing "Control Panel" in the Windows search bar and hitting Enter.
The Control Panel is a hub for many system settings, including tools for checking hardware. Finding it is the first step in our diagnostic journey.
Step 2: Access the Device Manager
Select "Device Manager" from the list of options in the Control Panel.
Device Manager lists all your computer’s hardware components. It’s a great place to see if any devices have issues, indicated by a yellow exclamation mark.
Step 3: Run Windows Memory Diagnostic
Type "Windows Memory Diagnostic" in the search bar and select the application. Choose "Restart now and check for problems."
Memory issues can cause all sorts of problems. This tool reboots your computer and checks your RAM for errors during the startup process.
Step 4: Check Hard Disk Health with CHKDSK
Open Command Prompt as an administrator and type "chkdsk /f" then hit Enter.
CHKDSK scans your hard drive for errors and attempts to fix them. It’s like a health check-up for your storage.
Step 5: Use Third-Party Software
Download and install a reputable third-party diagnostic tool like HWMonitor or Speccy.
Third-party tools often provide more detailed insights into your hardware’s performance and health.
After completing these steps, you’ll have a comprehensive view of your hardware’s status. Your computer will restart a couple of times during memory and disk checks, so save any work beforehand.
