Windows error code 43 is usually related to a direct hardware malfunction or error message. If a piece of hardware is installed on your computer and has a problem it will send this message to the OS and this error message will display on your screen.
Many Windows errors are fixable by making a few configuration changes within the operating system. Many of the driver errors that are commonly seen are able to be resolved by updating a driver. Windows error code 43 is not one of those errors. The standard methodology of troubleshooting using Windows or other software utilities will not provide a sufficient answer to this problem.
Error code 43 is an error code that is directly generated by a message from the hardware itself. Windows is informing you that the hardware has reported an error. You will need to work with hardware vendor resources to get the issue resolved.
The best place to start in getting this error resolved is by looking at the documentation that came with the device. You can search through the documents to see if the issue you are having is reported and if there is a recommended course of action from the manufacturer.
A secondary source of information would be to go to the vendor’s website to see if there is any additional information about the issue. You may be able to find a hot-fix or patch file that will resolve the error.
Many times your only recourse for these error messages is to get the device repaired or replaced. If your device is still under warranty, check with the vendor to see what your next steps should be. If the device is not under warranty, you will need to purchase a replacement or work with a technician to get the hardware repaired. There are some error codes that Windows cannot fix, and error code 43 is one.
