LEOKOEPP'S PROFILE

Hi, this is Leo, a new member on this forum. I just started playing this game Fallout 3 on Windows 10 PC. But recently I am experiencing a problem that I am unable to solve it. After a few minutes of gameplay, my PC's screen goes black. Strangely, I can clearly hear the audio.

Before that, I play several games on my PC. However, I have never encountered such a problem before. I dont know what could be the issue. Could someone please help me to fix the issue?
