Question Laptop Shutting down randomly

[viqzz07]

Hi, I have a ROG Strix G513RW, but when I run certain games like GTA V or CS 2 it randomly shuts down. I've added a cooling pad and disabled the CPU performance boost mode. I tried everything, updating the graphics driver, updating Windows, and even changing the CPU, GPU, and Mosfet thermal paste but it still doesn't work. Any solutions? Thanks
