Error Code 43 is one of several error codes of Device Manager. It is generated when Device Manager stops a hardware device because the hardware has reported an unspecified problem to Windows.

This general message may mean that there is a real hardware problem or just a driver error that Windows can’t identify as such, but as far as hardware is concerned.

It almost always looks like this:

Windows stopped this device because it reported a problem. (Code 43)
Detailed information about Device Manager error codes, such as Code 43, is available when viewing the device status in its properties.

The Code 43 error can be applied to any hardware device in Device Manager, although most Code 43 errors occur on video cards and USB devices such as printers, webcams, iPhones, etc. E. related devices.

Reboot your PC

Rebooting your Windows PC may solve the problem, because the device drivers can be booted the next time you boot up and the device can operate in the same mode as before.

It is worth a try, but only once. If you find that Windows Code 43 starts up again in the next session, rest assured that this is not a temporary hardware problem but requires more attention.

Remove the Lucid VIRTU MVP software

Since the last update of Windows, NVIDIA has officially announced that Lucid VIRTU MVP software is incompatible with NVIDIA devices and causes discrepancies that lead to various problems, including those that have arisen.
