Default Behavior

AMD K8 Processor Driver is a kernel device driver. In Windows 7 it won't be started if the user doesn't start it. If AMD K8 Processor Driver fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the AmdK8 service is not running because of the error.
