If you see this message on the screen with the error code 43 in Windows 10 or Windows 7 with the same code, you will find this guide helpful as it explains how to fix this error and bring your non-functioning device “back to life.” This error usually occurs with NVIDIA GeForce and AMD Radeon video cards, various USB devices (such as flash drives, mice, keyboards, etc.), network adapters and so on.

There is also another error message with the same code, but a different cause: Code 43 – device descriptor failed (we will talk about it in the next guide).

Windows Has Stopped This Device Because it has Reported Problems - Code43

How to fix «Windows has stopped this device» (Code 43)

Most guides for fixing this error you can find on the Web advise to check drivers of the device that was stopped by the system and test its physical condition (contacts, ports, etc.). However, if you are using Windows 10, 8.1 or Windows 8, we would recommend a very simple method before starting tinkering with drivers. It works perfectly for some components.

How to fix «Windows has stopped this device» (Code 43)

Reboot your computer (use the Restart option – not shut down and turn on) and check the device for the error code 43 in Device Manager (press Win+X and select the needed menu for that). If you don’t see the error in Device Manager and everything works just fine, but it appears next time after shutting down the computer and turning it on – you should try to disable Windows 10/8 fast startup. It is highly likely that after doing that the error “Windows has stopped this device because it has reported problems” won’t disturb you any longer. If this solution does not work for you, read on for additional information that will help you to fix the Code 43 error.

Updating and installing drivers correctly might help

If you did not reinstall Windows lately and the error never popped up before, we recommend you to open Device Manager, and open properties of the device stopped by the system due to the Code 43 error. In the “Driver” tabs you need to check whether the “Roll back driver” button is active or not. If it is clickable, then you can try to use it – there is a chance that the error appeared after automatic driver update that went wrong.

Now a few words about updating and installing drivers. We want to point out that the button named “Update Driver” in the Device Manager menu does not serve as a driver updater – it just checks for available updates. If you already used that function and got the message “The best drivers for your device are already installed,” it does not necessarily mean that it is true.

Here is a proper algorithm for installing or updating your drivers:

  1. Download original drivers from the official manufacturer’s website. If your video card was stopped by Windows, then you should go to NVIDIA, AMD, or Intel website, but if you have the error code 43 on your laptop (any device including video card) – you should check the website of the laptop manufacturer. In case, Windows blocks any integrated device on your PC, look for new motherboard drivers on the manufacturer’s website.
  2. Even if you have Windows 10 and there is only a driver for Windows 7 (Windows 8) on the official website – it does not matter, you can still use it, so start downloading without hesitation.
  3. Open Device Manager (Win+X and select it from the list). Find the stopped device. Right-click it and select “Uninstall device.” If the system will ask to uninstall drivers – delete them as well.
  4. Now run the official installer you downloaded earlier and follow the instructions.

In case, when the error Code 43 blocks your video card, you can try to uninstall all video card drivers and supporting software before the 4th step. For some devices it can be hard to find original drivers – for that scenario, Windows usually has a few standard drivers, so you should try another method:

  1. Open Device Manager.
  2. Find your device, right click it and select “Update driver.”
  3. In the next menu, click “Browse my computer for driver software.”
  4. Then click “Let me pick from a list of available drivers on my computer.”
  5. If you see more than one driver on the list of compatible drivers, you should select the one, which is not active right now, and click “Next.”

Check the device and its connection

If you have installed a new device, cleaned your computer/laptop recently, or switched ports, you need to check whether everything is connected properly now, when the error appears.

  • Make sure you did not forget to connect an additional power cable to your video card.
  • If a USB device is not working, it can be connected to a USB0 port, while it functions properly only with a USB 2.0 port (it happens sometimes, despite the backward compatibility of these standards).
  • If your faulty device is connected to the motherboard directly, you can try to detach it, clean contacts and ports, and install that device again.

Test your hardware

Sometimes the “Windows has stopped this device because it has reported problems” error with the error Code 43 may be caused by a broken device that is not functioning properly. We recommend you to test the device on another computer or laptop (if possible). If it behaves the same way and the error occurs – it means that you have hardware issues and need to either get a new device or repair the current one in a service center.

Additional information and other possible causes of the error Code 43

Here are a few other possible causes for the “Windows has stopped this device because it has reported problems” error:

  • The device is not receiving enough power for normal operation (usually – video card). The error might appear out of nowhere due to the power supply unit wear off and only in “graphics-heavy” video games.
  • The user has connected too many devices via one USB-hub or exceeded the limit of USB devices connected to one USB port on a laptop/PC.
  • Bad power management for the device. Open Device Manager and find your device that was stopped by the system. Check its properties for a “Power Management” tab. If that tab is there, you will also see an option “Allow the computer to turn off this device to save power” – uncheck it.
Additional information and other possible causes of the error Code 43
  • If you have the error Code 43 with a USB device (keep in mind that most integrated devices of your laptop such as Bluetooth adapter can also use USB ports for connection), go to the Control Panel from the Start menu and look for Power Options (If you can see it, switch “View by” to Large Icons). Then click “Change plan settings” – “Change advanced power settings.” Find the USB submenu and disable the selective suspend setting.

We hope that one of the methods described in this guide will help you to fix the “Windows has stopped this device because it has reported problems” error.
