Dell Inspiron 15 7000 Gaming keeps cashing

My Dell Inspiron 15 7000 gaming crashes everything I start playing a demanding game. It has an i5 and 1050ti. I have played these games before while watching a YouTube video on a monitor so I know it has no problem running the game. I can play for around 5 minutes until it crashes. Then the front light flashes a few times turns orange and the laptop reboots. I then get promoted with bios, and yes it is all up to date. Everything is updated and I have run diagnostics and it comes up with nothing. Any idea what’s happening and how to fix it?

Thanks in advance!
