I am having the a problem with my GPU, the first month of buying it was everything okay and after that when I run specific games like State of decay 2 or Velheim the screen turns into black and the GPU fans ramp up like full speed %100. I tried to add cooling fan I thought that fixed the problem, I was able to play for 2 weeks or so, then the problem back again but worse. Now even when I am not running games or anything the screen sometimes turns into black and the fans start ramping up and sometimes it turns into black without even fan sounds. I really don't know what's the actual issue here . the parts of my PC is(GTX 770 2GB , Powersupply Aigo 650w . CPU I5 3470)
