PC shuts down then restarts afterwards

[account_disabled]

My computer instantly shuts down as if someone pulled the plug, then restarts shortly after. As I mentioned before, it occures mostly randomly in matches, but it becomes more frequent after my computer has restarted from a shutdown. I have tried to monitor my temps during stress tests on the whole system and the GPU only, where they were around 80C for the GPU, and 40-45C for my CPU. From these temps, I would not assume its a temperature issue. I know that my Asus has a surge protection feature, but I tried to turn it off in the BIOS menu, but the problem still occurs, but this time without a power surge notification after the BIOS is done loading.

Any idea?

Please help.

Thanks!

I didn't find the right solution from the Internet.
