OP you need to think about a few things. Your DAW hasn't been updated in a while as far as I've seen. Additionally, it does not support Win10. You might want to start thinking about upgrading your DAW.
The best solution for a recording studio would be to stuff the PC in a soundproofed technical closet. That way, you don't need to worry about getting the PC anywhere near silent, it only needs to make less noise than your soundproofing can cope with.
