Sounds more like your integrated graphics is functioning fine, but the nvidia card is not being recognised at all.
Unless your actual cpu does not have integrated graphics, in which case something is way off. Most Chinese scams are using older 4 or 5 series nvidia cards with a custom bios, changing the identification from that 4 series card to a 750ti. I've not heard of any using radeon cards to do that since amd works differently to nvidia, to the same general results.
What cpu/mobo do you have exactly?
