Sudden black scree nduring play

Hello,


just reinstalled windows and got this bug 3 times already... after playing a while, usually during the fight (more usually after fight) using static strike + herald of ash on lvl20 are of effect my screen becomes black, but I can still hear sounds, which means game not completely crashed.
I can drink flasks (hearing sound) but alt tab and re-alt tab doesnt fixes it anyways, only solution to relaunch the game.


nvidia driver 365.19 (latest)

POE Settings:
poe resolution 1920x1080 windowed fullscreen
shadow quality: off
antialising: off
texture qty medium
2x antiisotropic filtering (though had similar problem with high quality and such)


RAM is running around 4.5GB out of 7, so should not be an issue
