Laptop not turning on

Recently got a monitor, keyboard and mouse so I decided to just use the laptop to run everything and just stick it in a draw underneath the table . I had no problems playing a few games like minecraft on my own. The second I got in a game of rainbow six seige it was choppy. Furthermore, at the end of the game the whole thing froze, a really loud sound started blasting through my headphones and supposedly my computer crashed. When I tried to reboot it, it refused and just stayed off. I decided to leave it and try again today. But when I came back to try and turn it on, all that would happen when I press the power button is you could barely hear the fans start up and the caps lock light would light up. It is also extremely hot and I have just realised I left it on power overnight. Whole thing will not turn on whatsoever no matter how long I hold my finger on the power button. I will disconnect the battery and turn off the fans for tonight but I was just seeing if there is any fix or if it has genuinely kicked the bucket. Thanks!
