several important pieces of information missing
brand and model of the microphone?
interface or other source of phantom power - is it turned on (phantom power that is)?
gain structures at interface level and daw level (your daw is irrelevant to this troubleshooting process but tell us anyway)
That sounds like a shitty USB mic. No hope.
any condensor needs phantom power by definition as the power provides the voltage and current necessary for the built in amplifier to work (48v @ 3mA = 0.144W)
in the case of usb mics they receive their phantom power via the usb power supply (5v @ 500mA = 2.5W)
so it is likely that the the annoying tic/hum is part of the usb power supply buss - i.e. you probably need a better power supply for your computer or you should bring the microphone in via a powered hub
