My OMEN 16 just blacked out

HP OMEN, AMD Ryzen 7 7840HS, 8GB NVIDIA RTX 4060. I was playing valorant on it this afternoon it just blacked out and it's not booting now. This has happened in past late December last year when my cousin was playing GTA5 it blacked out then as well but I connect it to a HDMI then to a TV it turned on. I tried it today as well nothing's working Help please
