I have a Neewer nw-700 and a lenovo ideapad 110 with windows 10. I connected the first xlr cable from my microphone to my phantom power box 48V with the input port, then another xlr cable from the phantom power box output to the 3.5mm cable to my computer, nothing comes up when I plug it in, and when i check the list of audio devices it doesn't come up and when i try to record nothing works. I plugged it into the headphone jack as there's no microphone jack, but when i plug in my headphones that come with a smaller microphone, it registers and i can use it as both headphones and a microphone, please help!
My microphone isn't being recognized by my computer
Firstly, the XLR-to-3.5mm cable that is supplied with the NW-700 and many other similar chinese "fake condenser" microphones simply does not work for most people, with or without a phantom supply.
So, don't get your hopes up…
The microphone itself does work OK with a proper XLR microphone input on any decent USB (or Firewire) Audio MIDI interface, such as a Focusrite Scarlett, Roland, Tascam etc.
From what you describe of the computer input, it's a new style that uses a four-contact connector like a smartphone, rather than the standard three contact sockets used on normal PCs for the last couple of decades.
To use a PC microphone with a four-contact socket, you need a headset adapter cable with two stereo sockets and the four way plug - eg.

That gives you the same separate headphone and microphone connectors as a normal PC.
For info, the NW-700 (and many other microphones advertised as "studio condenser" types) just has a basic electret capsule, similar to what's in a 99p "PC microphone" such as this:

They base the advert claim on the fact that the full name for an electret mic capsule is an "electret condenser".
Even quite a few expensive (200+) ones pull the same type of stunt or get creative and call them "permanently polarised" or something like that, rather than admitting it's an electret type.
The cheapest true condenser microphone I'm aware of is the MXL V67g at about £80 / $100.
