Render makes PC power off. (reproduceable)

I started working on one of my first complex scenes in Daz3d, and right after I started the render my computer shut completely off. The same as holding down the power button. After taking the items apart one by one, and rendering stuff seperately, I isolated the issue to the genessis 2 basic child. I was able to reproduce the problem with only the stock figure, no clothes, or other texture maps applied, nothing else in the scene. Has anyone seen anything like this before?

System specs may help idnetify the issue - that sounds as if something is causing a catastrophic crash, which isn't at all normal.
The system is an Alienware Mx17" i7-4910MQ CPU @2.90Ghz
32 Gig of Ram
Nvidea GeForce GTX 880M
Laptop? Alienware gamer?
HEAT...most likely graphics board overhating.
MJC,
This happens before real heat can generate, like 2-3 seconds into the render. I did some other renders last night, Genisis 2 &3 with complex scenes that took 3-4 hours each, and they all rendered fine.
I put the Genisis basic child in there, and that is the only thing, laptop powers off totally... about 4 seconds into the render.
As an experiment, I just changed the render mode from IRAY, to open GL, and it renders, I changed it to 3d Delight, it powers off, I keep it on IRAY it powers off.
A bit more testing, it is the Genesis figure no matter what I do with it. Placed figure, selected the 'Defaults' for the IRAY engine, PC powers off the second it starts to render it. Maybe someone from DAZ can comment.
Have you run it with GPU-z running, then film it so with a bit of luck you catch the settings as it crashes. In case info doesn't get logged.
Have you tried CPU as opposed to GFX card?
If it is OK with CPU but not with gfx card then you are narrowing it down; what do the logs say?
I'm not sure if the Alienware ones come with an aux fan for the graphics, some gaming laptops do, but what you are getting is a safety response...most likely either your aux fan, if it has one, or the CPU fan has bit the dust and since it's not speeding up, under load...the BIOS is killing the power to prevent going into deep fry mode.
I can render a plain Genesis without error. It's a stock answer, but try uninstalling and reinstalling Genesis Starter Essentials.
MJC1016,
I thought about that, however it makes no sense why I can render everything else, just not that character... I did a dozen renders last night of everything I used in the original, of individual items. Now I put a G3 character on there it works fine. I put only G1, and hit render, 2 seconds later crash.
Just to be safe...did you do the GPU-Z run?
If it is just that one character...then, no it isn't likely to be a fan or heat.
It sounds like something is happening in the video driver that the figure just happens to tickle. I'd update the driver before I suspect anything else.
GPU-Z run.... Hmmm ???? Ok confused face here, I am very new to DAZ and just getting back into this after many years. What is that?
GPU-z is a 3rd party monitoring/diagnostic program for video cards.

It's very useful for tracking down heat/power/memory problems.
The major factor with over heating is dust, try and clean the processor, if a laptop take to the menders to clean it.
If it's a desktop, maybe your powersupply is just too weak to provide enough power to run your system under full load. Can you give us some further details about your system's specs?
Don't think of it as a DAZ problem; look at it at a computer problem.
You need to create some stress on the comp; I'm not a huge fan of stress-testing as that is designed to run the computer more intensely than normal, which carries additional risk to the computer, especially when it might be suffering.
Have you tried rendering the same scenes using only the CPU?
Then only the GPU.
Do the problem(s) persist, or are they different or absent when only using one.
See attachment to ensure the GPU only option is selected; to change it to CPU only uncheck the GPU and check CPU above.
Note ... a machine with 32 gigs of ram... is most likely not a laptop, and whether it's gaming machine, it's still a very good computer.

As it happens when I upgraded to 4.8 ... I began to get crashes out of the render engine... only to the desktop ... forturnately.
---
being an old computer programmer I just ran tests until I found the single object that causes the crash.
---
Is the object at fault? I have lots of renders with it in the scene done in 4.6/4.7 ...
---
only in 4.8...does it crash... (and alone by itself).
--
same old computer... i7 920 with 24 gigs of ram... and I only use 3d delight because I don't use the GPU.
---
so has something changed in my computer? or in 4.8?
---
I've also had issues with extremely long times to delete objects from scenes....long enough so after 30 minutes I just close the program.
so long I just save what I want as a new scene subset and close the file
---
again I set up 4.6 on another computer... deleted in 5 secs.... same processor only 6 gigs of ram
----
so there are obviously some issues with 4.8....
---
first rule of programming ... add new features without messing up the old.
---
As for it being an issue with the computer...
Max, CS5, Hexagon, etc all are happy... only Daz is having issues...
or in the case of the renders 3d delight and then deleting of objects ... daz it self.
---
well, guess what... it renders in iray... but not delight
but it was created and rendered in delight originally.
---
in delight it crashes to the desktop in about 3 seconds...
---
added the duf file for anyone who wants to play with it.
---
but just like the fact that Jas narrowed it down to one model... I did the same... it's a bug, Daz.
--
picture one the built up bracket separated and rendered in iray...
picture two the entire set done in iray
picture three they are in the top trim on the right hand building...
and headers over the top story windows also crash in 4.8
Yes, crashes for me in 4.8.0.59 and in the last public beta rendering in 3Delight.
Hadn't tested in 3DL, I can give it a shot, I am guessing now that I have learned more, this is an IRAY issue of some flavor. I don't have an Nvedia card in my other system, so need to test with that on and off for the render. I had mostly given up on it and had been using CPU only on my desktop.
This may not be connected,,but,,
If you open the "Ready to Render" premade scene called "Day at the Beach" and then delete the G2F from the scene and nothing else, you can cause a CTD.
EDIT: note that you can delete anything you want, just not the G2F.
I've never had it shut down instantly but I've had my computer lock up totally and irretreivably immediately after commencing an Iray render with SubD set above level 3, on anything. Perhaps your genesis is defaulting to a very high SubD level and your rig just throws in the towel as soon as it sees it. Just a thought.
That sounds like a power management issue... and that on peak renders to are pulling more power than what the power supply is rated for and then shuts off your machine. I am curious if you aren't getting any warnings about overcurrent or tempertaure as well?
Digialus49,
There isn't that much time, it powers off about 20 seconds into the render, temp never even has time to get up there.
I am going to start messing with it and beating up dell/alienware this week.
That is most certianly an issue with the motherboard not handling the load properly. I'd get the computer looked at a service centre...
spent an hour on the phone with dell, they are replacing the 880M, and all the fans, and re-seating the heat sync on CPU.
Did this work?
Sure did done about 20 renders so far, no issues.
