The computer is a desktop with four drives. It is not a cheap one.
There is no date that give what you are referring to. If you know the codes for year produced, then that would be a great help. If the age of a computer has trouble with its OS X in some areas, such as Safari not automatically opening at startup, and not others even though using 10.10.3 successfully, then it would look like a software design problem. As you can see, the Model Identifier shows 5.1 which probably means May of 2011.
The Apple TV is a 3rd generation and the TV is HDTV.
Hope this is helpful to provide suggestions.
