I wish I was using my first post for something better...
 
Decided I was due for a new machine, so I ordered a bunch of parts off NewEgg, including a 1080.  Everything finally arrived, and I put it together on Tuesday.  It was late when I finished, so I went to bed.
 
Booted it up for the first time Wednesday after work.  I was playing around with some screensavers in DisplayFusion while waiting for Watch Dogs 2 to download.  That was the first time it happened.  While the screens were gone, I could still hear the Youtube video I was watching over the sounds of the fans.  Restarted.
 
Watch Dogs 2 finished and I played through the opening mission, only for it to happen again right after Marcus gets sacked.
 
Called it a night after that.  Tried it again in the morning.  It happened three more times, the last of which was right after I entered my Windows password.  RMA plz.

Well then, I'd say still not fixed!

Send it in!! I had it happen to a new 1 day old ftw3 1080ti elite 12ghz card that I bought from microcenter locally.

Was fine the first hour but something went on the card as in hour 2 it wouldn't last 2-3 mins in any game before it did the same.

Exchanged it the next day.. new one fine from there on.. this was prob 6 months ago.

I bought my card in August 2016 (FTW 1080). I went through 2 RMA's in the first couple of months since the purchase due to the black screen and fans at 100% issue, the 3rd card I received seemed to be ok. Then in July of this year the card blew, causing smoke and rendering the card unusable. Sigh, ok, another RMA a bit of a pain but what can you do. The card I received back from the RMA clearly wasn't new as it was a bit marked and looked used - whatever by this point it's 2 years old as long as it works ok I don't care. Then yesterday playing Destiny 2 I started getting the black screen issue! My screens lose input and go blank, the card fans spin up to 100% however the game still seems to be running in the background. 
 
Now my system configuration has completely changed since I was having this issue 2 years ago, I put in a new EVGA 750 GQ PSU, new motherboard and CPU. It simply cannot be anything other than a faulty card. By this point it will be my 5th card and I'm just at a total loss how this issue has not been sorted out at EVGA by now. They say it affected a small number of cards and they fixed it 2 years ago but they haven't. This is the first time I used EVGA as they have a good reputation, and yes through each RMA the customer service has been fine. But 5 cards is a total joke. Obviously there is a fundamental issue with the 1080 FTW cards as it's not just me - people are still having this problem 2 years later. 
 
I'm totally fed up with it now and considering cutting my losses and just purchasing another card with a different company. I have zero confidence in EVGA anymore as they seem incapable of controlling their RMA quality control process. 

thx
