In response to your PM: "I did the thing you said but doesnt turn on. Any other solution?"
If that failed then you may need to reach out to MSI and discuss a solution or warranty replacement. If your laptop died mid-game with no error messages and won't even power on then something fatally-failed internally. It would not be wise, at this point, to begin digging around in the internals of the laptop as warranty issues could arise from that. You could also consult a computer repair shop for a second opinion.
