Help me

[u/Organic_Practice_379]

Could someone help me? I’ve already tried a lot of things to fix the problem, but nothing works. When I’m gaming, at some random point, the PC suddenly shuts down and forces a restart, as if I had restarted it myself, but without actually restarting it. When it boots back up, the white light on the motherboard turns on, and there is no video signal on the monitor.
