MSI GT72VR 7RE Ice Storm and game reboot problem

Hello,

My new gt72vr 7re is rebooting by itself, randomly, but only happened in Ice Storm and pc game Bulletstorm Remaster,

Every single driver, bios, vbios, ec firmware, is updated, im using the last Windows 10 version as well.

I think this is not software related.

The reboot only happened, while playing Bulletstorm Remaster, limited at 90fps by the way, and 3D Mark Ice Storm.

Sometimes i can finish the Ice Storm bench without any problems, but today it was different, two reboots in the middle of the bench.

Important facts:

- No blue screen, no memory dump (windows options is set to create memory dump)
- Eventlog shows no errors before the reboot
- If i change in the windows options to no reboot if windows crash, the screen freezes and stays there
- Reboot Bulletstorm Remaster, 90fps limited - the game is not by any means demanding - , played 4 different games and a lot more demanding: no reboot
- It only reboots on Ice Storm bench, the less demanding benchmark of 3D Mark
- Lastest drivers/vbios/bios/firmware, Windows 10 last version, nothing running on background, no virus/malware
- Everything is default, cpu/gpu clocks, fans default, bios everything default

Reboot error, Eventlog:



Evento: Critico , Origem: Kernel-Power, ID 41 Tarefa 63

Event: Critical , Source: Kernel-Power, ID 41 Job 63

"O sistema foi reiniciado sem primeiro ter sido encerrado de forma correta. Este erro pode ter ocorrido porque o sistema parou de responder, sofreu uma falha ou ficou sem energia inesperadamente."

"The system has rebooted without cleanly shutting down first. This error could occured because the system stopped responding or lost power all of the sudden."

Google: "Ice Storm reboot":


"Spontaneous reboot (not bluescreen) is pretty much 99% surely a power supply issue.

It should be noted that Ice Storm is exceedingly harsh on the power usage of many GPUs - the framerate climbs to be so massive on modern GPUs that the GPU power draw can exceed what you'd see in games. A fully working system can happily take it, but I've also seen systems that are stable for everything else and do spontaneous shutdown on Ice Storm. And in every case trying with a better PSU gets around the issue.

So I guess the PSU in your case is kinda on the borderline - probably fine for most uses, but in extreme cases it can't quite handle the load."

Feniks, explain how a software issue would cause a 'kernel-power' in the event log and no BSOD and no minidump. How does software bypass the operating system and force the motherboard to issue a hard shutdown to the power supply?

I just can not see how it could be a software issue. I think it must be an issue with household electrical system providing dirty power, or failing PSU, or issue with GPU voltage regulators running high FPS at low load, or issue with high CPU load and low GPU load causing a power supply cross loading issue, or something. It just has to be a hardware issue. If I were the one with the problem, I would definitely try a different PSU.


I dont know what to say, this is really strange.
