Hello, I've started playing ESO and I can't stop getting black screens randomly while playing the game, forcing me to shutdown the game and open It again. I can still hear ingame sound so I guess It doesn't actually crash the game, just the visuals.
I have to say I play in windowed not full screen, I have yet to try in fullscreen.
The error appears randomly, maybe 30 seconds after logging in or 4 hours later, seems to happen more often in battlegrounds/Dungeon.

My computer specs are i5 6600k, 16gb ddr4, gtx970, SSD and Windows 10.
I've already tried the method in the "faq" for black screen when trying to log in but nothing changed, also tried lowering graphics and still the same as well

If anyone has any idea...
