Is my PCIEX16 slot dead?

Hi people. Here are my specs if that can help:

Intel Core i5-6600K 3.5 Ghz
Gigabyte GA-Z170XP-SLI Intel Z170 Express
GeForce GTX 970 4GB
Corsair Vengeance 16GB DDR4-2400 CL14
1x SSD Crucial BX100 250GB - 1x SATA HDD Seagate 7200.14 7200 RPM 2TB
LDLC QS-650+ ATX Quality Select (rebranded Seasonic Prime 80 Plus Gold 650W)

On friday while playing my screen turned black, with no more sound, I assumed first that my PC shut down for some reason (I did see the power button till on but didn't think much of it, I thought it crashed or something) so I restarted it and there was nothing on my screen. The machine seemed powered, I could hear it booting, just nothing on screen, no bip, nothing.

After freaking out and trying a few stuffs, I ended plugging my HDMI cable to the motherboard and suddenly I could see my screen waiting at the Windows login. So I assumed that my graphics card died. I wanted to upgrade my rig during the year so I started with a GTX 1080 that I just installed today. Except that it seems not working either (and yes I did plugged in my HDMI cable back to the GPU), I am seeing the same symptoms, the PC is starting correctly, I just have nothing on screen so I have to plug my monitor to the motherboard.

I ran some tests, Memtest86 (no issue with my RAM), Hot CPU Tester for 1 hour that didn't pick any error either.

My graphics card is correctly placed in the PCIEX16 slot, with the 6-pin and 8-pin connectors correctly plugged in, could this slot be dead? How could I tell it if that was case since I can't tell by placing a card in (and the probability that the new one is defective too seems low)?

Thanks in advance!

That's the only one PCIEX16 slot. Would I be able to tell with the PCIEX8 one?

Besides, if I had another slot it wouldn't tell if the first one was defective?

So I tried with the PCIEX8 slot and everything is working correctly, managed to get something on screen, installed my driver, checked a few games and no issue. I checked the PCIEX16 slot one last time and it still wasn't working so I imagine that the port is indeed dead (I've seen so many sites advising to check the power supply but I don't have a spare one, I ran various voltage tests though and no error was found).

I am now using the PCIEX8 slot and from what I've read the performance difference is negligible (and anyway my CPU is probably bottlenecking my GPU already) so I guess I'll keep it that way till I can upgrade my rig further down the year?
