Running hardware diagnostics on Windows 11 is kind of like taking your PC to the mechanic, but without the hefty bill. It’s a good way to get ahead of potential problems—that weird lag, random crashes, or just feeling like your machine isn’t quite as snappy as it used to be. Basically, these built-in tools help you spot issues with your RAM, disk, and other components before they turn into big headaches. Because, of course, Windows has to make it harder than necessary, so sometimes you gotta dig around a bit to find where those diagnostics really are. In this guide, you’ll get the lowdown on how to run them without resorting to third-party software, though I’ve got a few extra tips if you want to go deeper.
How to Run Hardware Diagnostics on Windows 11
Open the Control Panel
If you’re like most, finding the Control Panel can be a little… wonky. Just hit the search bar on the taskbar and type Control Panel. Once it pops up, click on it. It’s kind of old school, but still the hub for system tools. On some setups, the Control Panel shortcut can be a pain to find, so it’s easier just to start typing. Expect the typical windows to load, and you’ll be one step closer to running diagnostics.
Navigate to System and Security
Once inside the Control Panel, look for System and Security. Yeah, it’s a big chunk, but this is where Windows keeps its security and maintenance options. It’s kinda like the control room for your PC’s health. On some machines, you might have to toggle between “View by: Large icons” or “Small icons” to make sure you see everything clearly. Don’t get overwhelmed—just click through without overthinking it too much.
Access Security and Maintenance
Now, in that “System and Security” section, click on Security and Maintenance. This is where Windows tells you if anything needs attention. Scroll down a bit, and you should see an area called Maintenance. Here, Windows bundles most of its troubleshooting tools; it’s basically the dashboard for system health checks. Sometimes, the system’s going to flag issues automatically—other times, you’ll need to click “Start maintenance” for it to do a quick check-up.
Start the Troubleshooters
Once inside Maintenance, look for the Troubleshooting link or section. This is the real secret sauce, because here’s where Windows can run specific hardware checks. Click on Troubleshoot common problems, and a list of troubleshooter options should appear. For hardware stuff, you might want to look for options related to audio, graphics, or network—all of which can impact hardware performance. On some setups, you might have to click “View all” to see all the available troubleshooters. They’re not perfect, but they often catch what’s obvious.
Using Windows Memory Diagnostic Tool
This one is underrated but super useful if your PC feels jittery or crashes randomly. Just type Windows Memory Diagnostic into the search bar (yeah, same way as Control Panel), and click on the app that shows up. It’ll ask if you want to restart immediately or check during the next boot. Pick “Restart now and check for problems,” and your PC will reboot into a memory test. Not sure why it works, but on some machines, it seems to catch RAM errors that aren’t obvious otherwise. Expect a blue screen or a progress bar—don’t mess with the keyboard during the scan. Once done, Windows will start back up and give you a report in the System Tray or the Action Center.
Fun fact—on some setups, the memory test might fail on the first go or report errors that seem minor. Running it a couple of times can sometimes clear up false alarms or catch intermittent issues. It’s not 100% foolproof, but it’s better than nothing.
After the scan, Windows will have identified any memory or hardware issues. It’ll either fix the problem automatically or suggest next steps. Sometimes it’s just updating drivers, other times you might need to replace a stick of RAM or check your drives with a tool like Winhance.
Tips for Running Hardware Diagnostics on Windows 11
- Run diagnostics regularly—like every few months or if weird stuff starts happening.
- Keep your Windows up to date—lots of updates include improvements to these tools.
- If you want a really thorough check, consider third-party tools like CrystalDiskInfo for drives or HWMonitor for temps and voltages.
- Back up your important data first—sometimes diagnostics can crash or cause issues, just in case.
- Get familiar with your hardware specs (like RAM type, model numbers, etc.) so you know what to expect in the results.
Frequently Asked Questions
What’s the point of all these hardware scans?
They help spot problems before they turn into full-on crashes or data corruption. Basically, it’s preventative maintenance for your PC’s internals.
No third-party software needed? Really?
Yep, Windows has plenty built-in. The troubleshooters, Memory Diagnostic, and even performance reports are all ready to go without extra downloads.
How often should I do this?
Every few months or if things feel sluggish. Also, run them if you notice unexpected restarts, freezes, or error messages.
I ran diagnostics and it found a problem—what now?
Follow the recommendations—sometimes it’s as simple as updating a driver or running a disk check. If it suggests hardware replacement or more serious fixes, it’s probably worth consulting a pro or doing more intensive testing.
Any risks in running these tools?
Mostly no, but because Windows sometimes likes to be dramatic, keep backups just in case. Diagnostics are safe, but emergencies happen.

Wrap-up
Running hardware diagnostics on Windows 11 might seem a little tedious, but honestly, it’s nothing too crazy once you get the hang of it. It’s kind of a hidden gem that can catch a lot of issues early, saving time and frustration in the long run. Sure, some tests are more effective than others, and sometimes a quick restart fixes everything—but having the tools handy is never a bad idea. Keep an eye on your system health, and don’t wait until it’s too late to troubleshoot minor glitches.
