Hi, so when i start up a game like withcer 3 or ACBF i can play for 5-15 mins and then after that it black screens on me but maintains the sounds of the game and i can still move around and pause the game and still hear the sound of it but no visuals. im gaming in 4k res on a acer xb280k here is my pc full spec aswell.

After a while of searching through other forum questions and answers it seemed to be a bad driver, so i uninstalled my Geforce drivers and reinstalled and that seemed to fix it!
