Find speaker system Z313 overbearing loud buzzing noise

[DaveC_44]

did a great job of UNINSTALLING software and programs but the product won''''''''''''''''t be of much use to me being a new beginner.

How do I uninstall?

Looks like I need a serial number or something which I can''''''''''''''''t remember receiving?

Loud buzz from speakers has nothing to do with software.
