So working on putting a new computer together and when switching my GTX 960 SSC over from my old build into my new build I don't receive any signal to the monitor, all the fans in the system run and the ones on the graphics card spin up as well. On the old computer the card was working just fine. 
 
Parts used in new build-
Gigabyte B450M DS3H
Ryzen 5 2600
16 Gb DDR4 3000mhz  (Team Group Ram)
and a 500W PSU. 
 
I ended up taking this over to a friends place to swap out the gpu with his to see if the system turns on and putting in a GTX 1660ti lets the system post. We thought maybe the motherboard bios needed to be updated so we updated the bios to the latest version. Made sure windows was updated as well and tried putting the GTX 960 SSC back into it but no luck. The PC fans all spin up including the graphics card fans but the display doesn't pick up anything. We tried using the other ports on the back of the card for HDMI and display port connections but to no avail the card doesn't display anything. 
 
The card itself looks fine however I did notice a pin slightly chipped off, I would say about 80% of the pin is still remaining though. I'm thinking that is whats wrong with the card at this point.   Turns out that pin is supposed to be like that!
 
 
At this point I am thinking the card is just bricked. Is there anything else I can do to troubleshoot with it? Any advice would be much appreciated!

Post a picture of the damaged pins.

That pin is suppose to be like that. It's not the cause of the issue.

The old system was a prebuilt alienware r5 from a few years back. I can try putting it back into the old system but I'll have to take off the noctua cooler and put it back on the old one. Is there a different way to check its UEFI settings without going back to the old system? And yes I did try putting it in my friends computer in place of his GPU and it wouldn't display anything either.

Would I be able to put the 960 into another PCIE slot ( while his GPU is still connected) on my friends computer to change its UEFI settings?

Edit: I also dont know my own UEFI settings I'll have to check when I get back to my friends place. And excuse my poor knowledge of UEFI, it sounds like UEFI isnt saved on GPU's right?

So on the old alienware the included 140mm AIO died a year ago, so I bought a noctua air cooled one as a replacement. That was for the CPU. No changes made to the GPU. The OS was windows 10, updated from 7.
I'll try and do all the stuff you suggested, I'm working all weekend though so I'll probably get back to you by Monday or so it looks like.
Thanks again for the suggestion!

Alrighty I'll try that too!

Alrighty well the old alienware is dead that doesn't turn on no matter what I do, No worries with that.
 
The card does show up in my friends computer! 
(EDIT: The card is in another PCIE slot and a GTX 1080ti is acting as the main GPU in the system)
Going through GPU-Z and selecting it shows that the card is fine


Well I guess it mainly just shows that the card isn't completely dead right?
It also does show up in device manager too.

I guess my next question is do you think a Flash of the card will help fix it? 
Only thing is not really sure on what "flashing" a card really does.
 

Yeah I have tried all the connectors off the back of the card too.
Alright ill give that a shot thanks for the info!!
