Device Manager Error Codes

A Complete List of Error Codes Reported in Device Manager


Device Manager error codes are special error codes, accompanied by error messages, that are reported in Device Manager.

Error codes in Device Manager are generated when the computer is experiencing device driver issues, system resource conflicts, or other hardware problems.

Note: Device Manager error codes are completely different than system error codes even though some of the code numbers may be the same. If you see an error code outside of Device Manager, it's not a Device Manager error code.
