[SOLVED] Could power supply cause my pc shut down but after 2-3 minutes it starts by itself

Last 2 days when I play PUBG (greedy for resources game) my PC shuts down and after 2-3 minutes it restarts by itself. IF I try to force the PC to start with a button , nothing happens till it switch on by itself . This is happening only in game . I did a stress test but PC working fine under the test . What could be the reason ?
AMD Ryzen 5 1600x 3,6ghz/am4 ,SSD 850Evo m2.250gb, geforce GTX 1070,msi x370 gaming plus ,2x8gb ddr4 3000mhz corsair venegate lpx , power supply 750W bronze (cooler master)
PC was working fine for 3 years !

It could be that your CPU is too hot. Is it's cooler running OK?

Are you able to get temp readings?

It can, some PSU have this Fuse that is temp regulated when it's too hot.
when you run a stress test, is that a CPU only stress test? while gaming stress CPU and GPU.
check if fans on PSU is ok, it could be a dying unit too.

Most coolmaster PSU's are garbage.

Stress test the CPU and video card at the same time while monitoring temperatures.

Is the ram you're using also listed on your motherboard memory QVL?

Can you try again afetr doing a bios reset?
