Hello,
Recently while I was playing a game my screen blacked out but the game was still on with sound and sometimes it would turn back on for some seconds and then black again. I saw that this happened when the gpu reaches 70 degrees.
In other occasions the screen never goes black. The only time it does is when I start up games and the gpu gets to 70 degrees.
When I play games that don't make the gpu that hot like Rocket League, the black screen never occurs.
So to sum this up. When I play games, in around 20 to 30 minutes of Gameplay the screen goes black. The temperature is mainly 60 to 70 degrees. In other occasions like browsing, editing or light gaming it does not happen and everything is normal.
Note : I have not cleaned the pc in months or maybe a full year. So it is full of dust. I will clean it up.
Note 2 : I do not have any fan except the gpu's 2 fans, the cpus fan and a rear fan that came with the case. I just bought 1 fan for the front panel.
