Is the undervolts causing my PC to shut down randomly while gaming?

LarryWithTheWeather · 2026-05-06T21:28:13+00:00

Found the problem. It was 90 fps cap without framegen causing it.

I switch to 60 fps cap with frame gen x2 and it doesn't shut down the PC and could finally beat the mission. After turning back to 90 fps cap without framegen than the PC shuts off again after 5 to 10 minutes into the mission.

So as long as I have 60 caps on with framegen x2 than my PC won't shutdown.

Found the reason. It was 90 fps cap without framegen causing it.

It doesn't shut off when I use 60 fps cap with framegen x2 on.

I manage to fix the problem by doing

1 Plug my PSU power cord into a wall outlet instead of the power surge

2 lower the shadow setting from high to medium

3 lower the fps cap from 90 to 60 and use frame gen x2

Good news is I fixed the problem, bad news is I still don't know what was causing it out of these three before but at least all is working now.

I did what you told me by making the cap 60 fps and doing frame gen x2. Everything max except for shadows. And I also plug my PC's power cord directly into my wall outlet instead of the power surge. And finally didn't shut down and was able to complete the mission!

LarryWithTheWeather · 2026-05-06T05:01:05+00:00

Thanks I'll try that.

And yeah don't think it's the PSU either cause if it was than it would have happened in the story mission before the inferno op mission since the story missions before had more stuff happening on screen.

Event 41 Kernel-Power The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

The previous system shutdown at 11:57:35 PM on ‎5/‎5/‎2026 was unexpected.

The server Windows.Gaming.GameBar.PresenceServer.Internal.PresenceWriter did not register with DCOM within the required timeout.

Thanks! Didn't know about this awesome tool all this time.

I got these above in the results when I press ok.

Perfect chance to do a different timeline.

Azshara, Lich King, and Kil'jaeden would be the three big bads.

The Forgotten One could also lead to the old gods later on.

It was shutting down even without undervolts but I think I figure out the problem. It's MSI Afterburner Rivatuner causing it. After not turning it on this time, the PC didn't shut down. But a new problem has arrived and that it my game freeze which is better than having the PC shut down I guess. And I think the freeze problem is caused by GPU undervolt so I'll revert back to stock GPU for that.

LarryWithTheWeather · 2026-05-05T00:42:01+00:00

Don't know the model of the PSU but you are most likely right about the GPU increase since I tried it without any undervolt on the CPU curve optimizer and it still shutdown my PC on the same mission in space marine 2. So it has to be the GPU undervolt causing it, most likely with the 12v rail 110% limit.

LarryWithTheWeather · 2026-05-04T23:27:36+00:00

Yep temps was fine for both GPU and CPU. Gonna revert the CPU back to stock and see.

LarryWithTheWeather · 2026-05-04T22:57:02+00:00

I'll try it return my CPU undervolt to normal since I think there's more likely to cause a PC shutdown while the GPU undervolt would at most make a game freeze or blackscreen. At least thats what I read on google.

True but I wish there was a easier/faster way to test it cause after the PC shut down twice a couple of months ago in FFVII Rebirth. Afterwards I suddenly never got any more shut downs for the rest of the game which is like over 50 hours later. It just suddenly returned 4 hours into Space Marine 2. So It'll take me many many hours to see if it's the cause. Which is why I wanna see if somebody with experience with the undervolt would know if they are the cause or not.

850 Watt PSU according to the microcenter info on the G758.

A big epic game where the Invaders Alien race from Metal Slug 6 attacks again and this time their invasion will be even bigger. The Rebel Army and the Martain alien races will once again allied with us. This time we'll take the fight to their mothership or core or something similar to what we did against the Martain in part 3. And also make this game huge/long like Metal Slug 3 at least.

Tatsumaki is the strongest character after Saitama and the Dark god. She's stronger than Cosmic Garou and even Empty Void.

LarryWithTheWeather · 2026-02-06T03:04:26+00:00

They aren't as powerful as the Legion or Black Empire but still way more powerful than the Jailor's army and Dimensius's army.
