Question PC shuts down and reboots without warning.

[KanjiroS]

Just recently, my pc has this problem of shutting down and rebooting after running games like Monster Hunter Worlds and warframe. I tried paying attention to the temps but all of them arent any different from months ago before the problem occurs. Games like roblox takes some time before it shuts down and reboots back, as if Monster hunter worlds, its shuts down immediently when it loads into the start screen. I tried running furmark and heaven benchmark, it shuts down and reboots within a second of the test starts. There is this loud screeching sound from my psu when my pc is under light or heavy load. Could it be that my psu is the cause of the shut down and reboots?

My pc can stay on all day without problem if i dont play any of those games that i mentioned.

Welcome to the forums my friend!

Please post your entire system spec including PSU make and model (and how long you have had said PSU).

But initial glance would say that you need a new PSU!
