How to Fix a Code 41 Error
Try these steps in order until the error is resolved:
Restart your computer. There’s always the possibility that the error was caused by some temporary issue with Device Manager. If so, a simple reboot might fix the problem. Make sure the device is properly connected. If it’s inside the PC, check to make sure all the connections are firmly seated and any connectors are properly connected. If this is a newly installed device, check the manual to make sure that everything is connected in the correct fashion to the appropriate connectors on the motherboard. If the device is external (i. e. , connected with a USB cable), try using a different cable. Use System Restore to undo recent system changes. If the device was previously working, undo any recent changes to the Device Manager by using System Restore. Roll back your drivers.

Remove all associated drivers and software, then reinstall or reconfigure the device. A problem with the device itself might be causing the code 41 error, so you might need to replace the hardware. It’s also possible that the device is not compatible with your version of Windows. You can check the Windows Hardware Compatibility List to be sure. If you’re sure that a hardware problem isn’t causing this particular code 41 error, try a Windows Startup Repair.
