Basically I have a RX 580 and i have no problem running Fortnite at all doesnt crash has good frames but when i try to launch H1Z1, CSGO or Sea of Thieves my screen will go black after a little while for example i could run csgo for about 20-30 mins before this happening then sea of thieves goes straight away i dont think its an issue with cooling as i have my gpu fans set on 100% and my cpu doesnt seem to be going to high temps around 57-64 but what i dont understand is why my pc stays on but all my sound goes and my control over the pc goes then the picture on the screen goes. Could this be down to a bad GPU or something wrong with my pc aka Drivers or something? and also sometimes my screen flickers but very very rarely. if anyone can help would be extremely appreciated.
