Check if there is a BIOS update for your board. As well I have seen some Gigabyte board have to have legacy mode enabled in BIOS for some cards to work.

I've noticed that when I plug my VGA into the DVI adapter my monitor has black screen, is it meant to do that?
Maybe the card isn't dead yet. I've recently had the same problem with my R270X and it turned out to be a partial PSU failure. So try to plug another PSU to the PC.
It may just be faulty. I had this problem with a Radeon 5850. The only solution was to exchange it for a new one and it worked.
I've tried returning it but they said it worked fine.
Did they show you it was indeed working fine?
The shop I took it back to, Microcenter, took my word for it. I was well within their 2-week return period as I tried to install it the day I bought it. All I know is the new one worked and the one I returned didn't.
