Frequent crashes to desktop after ~30 minutes in a new PC game

[NoahLS]

I'm experiencing frequent, seemingly random crashes in a major new PC game, usually after about thirty minutes of play. My system exceeds the recommended specs, I've updated my graphics drivers, and verified the game files, but the issue persists without an error message—the game just freezes and closes to desktop. For others who've solved similar instability, what troubleshooting steps beyond the basics revealed the culprit, such as specific background processes, Windows power settings, or hardware monitoring tools that identified an overheating or power issue?
