Pc restart when full screen game

[SLOTHINSPACE]

Hello my dad pc has started recently automatically restarting when he launches games, I tried figuring it out, he used 2 monitors when I disconnect the 2nd one and launch the game the issue does not seem to happen. Any suggestions would be great. Maybe something to do with a gpu driver. But honestly I’m not the best with computers 

 

These are the important specs 

Monitor

Samsung G9 49 inch 

1440p 165hz secondary 

I9 10900x 

RTX 3090 

ROG THOR 850w psu 

32gb ddr4 3200hz ram

Anyone got any ideas ?

Is it an OS crash? A hard reset? Describe exactly how does the system restart?

 

My first though is maybe that 850W PSU is on the edge of being able to power those specs, if it is hard resetting.

yes so its only just started he has pushed his pc with the monitor he has at 240hz 1440p no problems, when he starts a game then full screens, the pc just re boots, no error or nothing just as if you restart the pc but without the restart screen. If that make sense

So i imagine a hard reset if its not displaying the windows restart window

Yea, if it just cuts power and restarts, that's a hard reset.

Any ideas of what could be the issue and a fix, as i said this has only just started to happen his pc has been fine, since he built it, and now starting to cause some issues ?

I'm really thinking it might be the power supply. 850W should be just about enough for that system under full load, but sometimes components will have spikes of high power draw which go above their TDP. That might be happening here. Contrary to popular belief, power supplys from reputable product lines won't burst into flames the moment they're stressed to hard. They almost always cut power to protect themselves and the components being powered. Connecting a second monitor might be pushing the graphics card hard enough for it to spike above how much power the PSU expects to provide, which will trip the safety and hard reset the system. Though the issue could be a thousand other things, this is what I think is most likely. Maybe try setting power and clock limits in MSI Afterburner. It's a great program form managing that kind of stuff. I don't know much about the Nvidia control panel, but it might also have similar options.

Right okay what about a driver maybe use DDU and installl a old driver to see if that has anything to do with the issue ?

It wouldn't hurt to try.

Just seems very strange to me he has pushed that  computer any game no problem and all of a sudden this happens I can’t think of a reason why

Possibly a Windows or driver update, or component degradation.

I agree with @LloydLynx Sounds like a PSU issue and those 3090s are very spiky under load (from what i gather from reviews)  How old is the PSU?  I've seen a lot of people say 1000w is about right for a 3090 and coupled with the 10900X that's a LOT of draw under load for an 850
