My notebook won't turn on or show any signs of life.

I overclocked the gpu and cpu to get more power and was doing it consistently for about 2 weeks. I used a very powerful cooling system so the laptop didn't overheat, but it would occasionally turn off. I eventually stopped overclocking but then the laptop would be extremely hot and sometimes it randomly turns off even when I didn't do anything- Like I would just turn it on and 5 minutes later its hot asf without me doing anything- but I kept managing it. One day I was playing pes 2017, a none demanding football game, and the laptop turned off, and hasn't turned back on since then. It doesn't boot, no lights turn on, even the charging light doesn't light up when I plug the charger in. I need help.
