GPU working, not detected by PC

[zAsdf0]

So I installed:
I5 6400
asus z170-e
Corsair vengeance DDR4 RAM
MSI gtx 1060 6GB

Everything is working fine except that my pc isn't recognizing my GPU (the fans of the GPU work, etc.) and I am running my display through the GPU.
I didn't format, just uninstalled my previous AMD GPU's software and installed Nvidia drivers and still not picking up.

Could it be software or something in BIOS settings?

It's possible remnants of the old driver has an effect or new drivers aren't working properly. Did you clean install the new driver? If you haven't then it's worth a try.

On an aside, what does Device Manager see under display adapter?

Device manager asked me if I wanted to activate my GPU -.-

Haven't come across that before.

Does it solve the problem after activation?
