So I've seen a few threads about black screens, crashing, etc. I think the issue I'm having is different. I have an EVGA GTX 1070 FTW (with latest November 3rd video BIOS installed). On some games, when I quit them, I get a black screen instead of my desktop. Everything seems to respond properly (via the keyboard), the monitor acts like it is getting a signal (it stays turned on and doesn't say "No Signal"), sound still works, etc.
 
The current workaround is to press Fn+Pause on my keyboard (Razer BlackWidow) to put the computer to sleep, wake it up by pressing the power button, turn the monitor off and on, and my computer is sitting at the lock screen. Log back in, and I'm good to go like nothing happened.
 
I've tried other things like hitting Alt+Tab, Alt+F4, Ctrl+Alt+Del, etc., turning the monitor off and on, and so on. I'm running the latest NVIDIA drivers. I've had the computer for a couple of months now, but this only started in the past few days. It seems to happen fairly consistently on certain games (Braid, Dark Souls III, & Star Wars: The Old Republic for example), but never on others (I have like 80 games installed).
 
Any suggestions please? Has anyone else seen this issue?

So this issue didn't occur on the original vbios?

That was my original suspicion as well. However, I remembered that it did happen one time before I applied the BIOS update. It was during that first time that I established the workaround described above.
 
Card is working great otherwise (before and after new BIOS). No CTDs, TDRs, artifacts, etc. using factory overclock.
 
Thanks for checking!

Here are my suggestions...
 
#1 Try a different display cable if you haven't already. If using a display port cable make sure the cable is vesa certified.
#2 Inside the nvidia control panel under manage 3d settings, global settings, set power management mode from optimal to adaptive. Reboot PC
#3 Retest for black screens.

Thanks! Will test and see how it goes...

No problem. You might want to try the other dp outputs on the card as well. 

Getting exactly the same issue in here (Just started to happen recently but before bios update). Clueless to the moment as what might be. Although i have some suspicious about nvidia recently released flawled whql drivers OR Windows update packages because my system didn´t changed from a while and only new drivers were installed. Tried already 2 monster hdmi cables with same results.

I´m seeing a lot of this issue in nvidia forum and microsoft support forum but with no answers until now.

Thanks, flaviossa. Sucks you have the issue as well, but glad I'm not the only one I guess. Found a post in the GeForce forums suggesting it is caused by G-SYNC. Do you have a G-SYNC monitor as well? I'm going to try turning that off to see if that is causing it, along with Sajin's power management suggestion.

Okay, turning off G-SYNC fixes the issue for now, which is a bummer. I've actually managed to forget how nasty screen tearing can be in some games. Here's hoping this is a temporary hiccup in the NVIDIA driver and that they get it squared away ASAP. I'm going to try and chime in on the GeForce forums as well to try and add me to the list of those affected. Hopefully, NVIDIA is taking note...

I run a g-sync screen too. Never had this problem.
