gigabyte gt 440 code 43

Code 43 is an error specific to the Windows Device Manager and is a clear indicator that there are errors with the driver of the offending device. A Code 43 error is generated due to errors reported by the driver itself meaning that this error is a software problem. The error could mean many things including corruption or misconfiguration but the real cause of a Code 43 error is very uncertain. A Code 43 error is produced when the driver reports an error but is not specific about the exact nature of the problem.

Causes: The driver is not installed.
The driver is missing.
The driver is out-of-date.
The driver is corrupt.
A previous attempt to update the driver failed.
The device is not configured as the default device.
The device is not plugged in correctly or all the way.
The device is damaged.
