Identify malfunctioning your hardware drivers with Windows Device Manager on Windows 7

How to identify missing or malfunctioning drivers with Windows Device Manager

To see which of your devices have a missing or malfunctioning driver:

Step1: On your keyboard, press the Windows logo key and R at the same time to invoke the Run box.
Step2: Type devmgmt.msc and click OK.

(There are other ways to open Device Manager; it changes depending on your version of Windows. But the above method works for all versions of Windows, including Windows 11, 10 and 7.)

Step3: Expand a category (e.g. Display Adapters) to see the devices in that category. If you see a yellow triangle or question mark next to a device, Windows has detected that it has a missing or malfunctioning driver.

Step4: If you see this yellow mark, you can try to update or reinstall the driver.

What are drivers?

Drivers are like interpreters between Windows and your devices. For example, when Windows needs to display something on your monitor, it sends a command to your graphics card, and your graphics card then displays what Windows wants on your monitor.

But Windows and your graphics card don’t actually speak the same language. To understand each other, they need a translator. That translator is called a driver. It takes the Windows command and translates it into something your graphics card can understand. Your graphics card can then do as it’s told, and display the right thing on your monitor.

Similarly, if your graphics card needs to send some sort of response back to Windows, the driver translates the response into something Windows can understand.

In this example, what we’re talking about is a video driver, but your computer has many other drivers on it too – one for each device. Your speakers, your printer, your mouse, your USB hard drives, your network card, your keyboard and so on – they each have an associated driver.

And without all these drivers, none of your devices will work.
