Razer Blade Pro 17 2017 4K Settings

Good day I bought a 2017 model Blade Pro 17 4K laptop and the laptop doesn't work any more than it works. I would like to know how to set it correctly, because the processor overheats to the level of 98 degrees. When playing for about 5 minutes, the laptop shuts down completely due to insufficient power supply. Can anyone tell me how to use the laptop to make it work??? And I also wonder if you happen to everyone and why did Razer release such a product into the world when immediately after buying and playing it turns itself on or plays at 98 degrees??? I tried undervoltage of the processor and data multiplier from 40 to 34 and the processor reaches 91 degrees. I had to drop the graphics card by 200 mhz so it wouldn't shut down on any source. What performance does such an undervoltage laptop have???
