How To Fix Code 43 Errors
Windows has stopped this device because it has reported problems. (Code 43) error
The Code 43 error is one of several Device Manager error codes. It is an error message that occurs when Device Manager has stopped a hardware device.
This generic message may mean that there is a real hardware problem, or it may simply mean that there is a driver error that Windows cannot identify but the hardware is affected by it.
How To Fix Code 43 Errors
Windows has stopped this device because it has reported problems. (Code 43)
- Restart your computer if you haven’t already, there is always a chance that error Code 43 is caused by some temporary hardware issue. If so, restarting your computer may fix the Code 43 error.
- Plug the device into a different computer and then properly eject from there. Plug it back into your computer to see if that fixes the Code 43 error.
- Did you install a device or make a change in Device Manager just before you got the Code 43 error message? If so, it’s possible that the change you made caused the Code 43 error. If you can, undo the change, restart your computer, and then check again for the Code 43 error.
Depending on the changes you make, some solutions might include:
- Uninstall or reconfigure newly installed device
- Rolling back the driver to a version prior to your update
- Using System Restore to undo the latest changes to Device Manager
-
Disable the device and then re-enable it. This may sound like a very simple fix, and that’s why. However, this path might be all it takes for the computer to fix the Code 43 error.
- Reinstall the device drivers. Uninstalling and reinstalling the drivers for the device is a possible solution for the Code 43 error.
-
Update the device’s drivers. Installing the latest drivers for the device may fix the Code 43 error.
If updating the drivers removes the Code 43 error, it means that the stored Windows drivers you reinstalled in Step 4 are probably damaged or incorrect drivers.
-
Install the latest Windows service pack. One of Microsoft’s service packs or other updates for Windows may contain a fix for anything that can cause the Code 43 error, so if you haven’t been fully updated, do it now.
-
Update the BIOS. In some cases, an outdated BIOS can cause a specific problem with a device that causes Windows to report a problem – hence the Code 43 error.
-
Replace the data cable connecting the device to the computer, assuming it has it. This potential fix for a Code 43 error is often helpful if you’re seeing the error on an external device like a USB or FireWire device. Change hardware. A problem with the device itself can cause the Code 43 error, in which case replacing the hardware is your next logical step. In most cases, this is the solution to a Code 43 error, but try some of the easier and freer software-based troubleshooting ideas first.
-
If the Code 43 error appears for a USB device, purchase a powered USB hub. Some USB devices require more power than the built-in USB ports on your computer can provide. Plugging these devices into a powered USB hub solves this problem.
- Change hardware. A problem with the device itself can cause the Code 43 error, in which case replacing the hardware is your next logical step. In most cases, this is the solution to a Code 43 error, but try some of the easier and freer software-based troubleshooting ideas first.
- Another possibility, although very unlikely, is that the device is incompatible with your version of Windows. You can always check the Windows HCL to be sure.
