The Code 43 error is among the Device Manager error codes. It appears when Device Manager ceases a hardware device because the Window detects the hardware has some unspecified error.
What Does an Error Code 43 Mean?
This generic message may indicate a genuine hardware issue, or it may simply indicate a driver fault that Windows cannot recognize but is impacting the hardware.
Almost always, it will seem as follows:
Viewing a device’s status in its attributes gives you information about Device Manager problem codes like Code 43.
Any hardware device in Device Manager may experience a Code 43 issue. However, video cards and USB devices like printers, webcams, iPhones, and associated accessories seem to experience this problem more frequently.
Note: Device Manager is the only application that may generate error codes. You shouldn’t address the Code 43 error as a Device Manager issue if you see it elsewhere in Windows because it’s likely a system error code.
A Code 43 Device Manager problem may appear on any Microsoft operating system, including Windows 10, Windows 8, Windows 7, Windows Vista, Windows XP, and more.
Fixing a Code 43 Error
To fix a Code 43 issue, perform these steps in the correct order. Since this warning is generic, usual troubleshooting techniques should be used first.
- If you haven’t already, restart your computer. There is always a chance that a transient hardware issue brought on the Code 43 error you are experiencing on a device. Restarting your computer may resolve the Code 43 issue if this is the case.
Note: Some users have also claimed that if their Code 43 warning comes from a USB device, totally shutting down and restarting their computer fixed the issue. When using a laptop, turn it off and remove the battery. After waiting, replace the battery and turn the machine back on.
Important: Connect the device to a separate computer and properly remove it afterward. Check whether the Code 43 issue is resolved by plugging it back into your computer. Before continuing with the more difficult procedures below, test this on another computer if you have one available.
- Before the Code 43 error showed up, did you install a device or make any changes in Device Manager? Your update might have brought on the Code 43 problem if such were the case. Restart your computer, undo the modification if you can, and then check for the Code 43 error.
- Some solutions, depending on the modifications you made, might be:
- Deleting or changing the settings on a newly installed device
- Reverting the driver to a previous iteration before your update
- Making recent Device Manager-related changes unintended by using System Restore
- Turn off the device and then turn it back on. This phase gives Windows a chance to evaluate the device configuration from scratch. It may seem like a pretty straightforward solution, and it is. However, the computer could only require one process to fix the Code 43 issue.
- Reinstall the device’s drivers. A possible fix for a Code 43 issue is to uninstall the device’s drivers and then reinstall them.
Important: As part of the driver installation, delete any device listed in Device Manager’s category for Universal Serial Bus controllers if a USB device produces the Code 43 problem. Any USB Mass Storage Device, USB Host Controller, and USB Root Hub are included.
Note: Updating a driver is not the same as properly reinstalling one, as described in the above procedures. The present driver must be entirely uninstalled before Windows can reinstall it. This is known as a full driver reinstall.
- Update the device’s drivers. It’s also conceivable that updating the device’s drivers will fix the Code 43 problem. Updating the drivers successfully removes the Code 43 problem, indicating that the previously installed Windows drivers from Step 4 were either ineffective or incorrect.
- Install the newest Windows service pack. If you aren’t completely updated, do it right away. One of Microsoft’s service packs or other updates for Windows may contain a repair for whatever could be generating the Code 43 issue.
- Update the BIOS. The Code 43 error might occur when a device reports a problem to Windows because of a specific fault caused by an outdated BIOS.
- If the device has a data cord connecting it to the PC, replace it. This possible Code 43 error cure is typically helpful if the error is occurring on an external device, such as a USB or FireWire device.
- If a USB device displays the Code 43 error, buy a powered USB hub. Some USB devices require more power than the built-in USB ports on your computer can supply. This problem is resolved by connecting the devices to a powered USB hub.
- Change out the hardware. Changing the hardware is the next obvious step if a hardware issue is to blame for the Code 43 error. Most of the time, this fixes a Code 43 error, but try the simpler, cost-free software-based troubleshooting methods first. If you’re certain that a hardware issue isn’t to blame for the Code 43 error, you might try a Windows repair install. Try performing a clean Windows install if that doesn’t work. Although we don’t advise doing either before replacing the hardware, you might have to try them if you have no other choices.
- The device might also not work with your version of Windows, though this is less likely. To be certain, you may always check the Windows HCL.

SYSTEM THREAD EXCEPTION NOT HANDLED: What does it mean?
When a hardware driver fails, Windows experiences a BSOD (Blue Screen of Death) error. A software driver that is damaged, out-of-date, or improperly installed is often to blame for the failure.
