Geforce GTX 1070 Gaming X 8GB not recognized

[icesloth7]

Building a PC (for the first time) and running into issue where the motherboard isn't recognizing the GPU. When the HDMI and DP cables are plugged into GPU, monitor shows nothing. When the DP is unplugged and HDMI is plugged into motherboard, the onboard gpu displays properly to the monitor. So it's not the monitor which is the problem.

I've already installed the drivers for video card, made sure the PCIe slot is selected in BIOS, tested system without GPU installed (it displays fine). When I boot up PC, the GPU fans start spinning but then stop because it knows it's not being recognized by motherboard - which I think is expected behavior. BIOS screen says it's recognizing the onboard GPU only in system information.

Here's my system spec:

CPU: Intel Core i5-6500 3.2GHz Quad-Core Processor
Motherboard: Gigabyte GA-H110M-A Micro ATX LGA1151
Memory: Corsair Vengeance LPX 16GB (2 x 8GB) DDR4-2400
GPU:MSI GeForce GTX 1070 8GB
Power Supply: EVGA SuperNOVA NEX 650W 80+ Gold Certified Fully-Modular ATX
OS: Windows 10

Any ideas what I could be missing? I hate to think I got a lemon GPU, but running out of ideas of how to troubleshoot this with my limited experience in building PC's.

Can you try a different GPU in that slot, or a different power cable in the card, or a different port on the card?

Although it's not the optimal answer, you can also potentially try the 1070 in a secondary PCIe slot to see if it just turns on.

Figured out what I was missing.

I had to connect the internet and download the latest drivers available online, as the disc provided by MSI did not include the latest drivers :/

GPU is connected and working like a charm!
