Black screen in Daz

I made a post earlier but we didn't reach any solution so I try another go with more information.
Out of the blue a few weeks ago Daz "crashes" for me. Its not a blue screen crash because things in the background are still going. E.g if I'm listenting to a Youtube podcast I can still hear it going on and light is still being emitted from the PC and my peripherals. It just turns off the monitors. Only way to fix it is by doing a hard-reset on the PC. I've seen some similar threads were people say its a VRAM issue. Yet why would this happen to me out of the blue? Sure I only got 10gb of VRAM but that has always been enough and these aren't resource intensive scenes we are talking about. I've even done close-up 6 charachter renders before and it have worked fine. It can even occur during me playing around in Filament. I've been using Daz3D for a couple of years now, so I don't really get why this issue have popped up. I can't really troubleshoot the issue cause the screen turns black so I can't tell if Daz is giving me an error message or not. This issue is Daz exclusive. Meaning it doesn't happen to me when I render in Blender. I'm thinking its software based yet the only thing that's new is me downloading assets and updating Daz3D. But it happening out of the blue makes me think it must be something related to that but I don't know and I don't want to give up on my main 3D software. I read some other post about people saying that XTransfer plugins or OOT hair assets causes crashes, I have both of them.
Specs:
AMD Ryzen 5600X 6-Core Processor, 4200mhz
Corsair 16GB (2x8GB) DDR4 3600MHz CL18 Vengeance
ASUS GeForce RTX 3080 10GB TUF GAMING OC
PSU produce 900W, maybe a bit low for this spec but it has never been an issue in the past.
What I have done:
Updated to the latest version of Daz3D
Did a fresh install of the latest Nvidia driver with DDU
Benchmarked and troubleshoot both CPU & RAM (which are stable at 50c)
Cleaned the PC
Checked temps during load and they are about 70-80 at their most intense

It sounds like perhaps the graphics card is overheating maybe? The monitor switching off after a while of rendering without it being a crash does kinda sounds like it could be that. I know you have said you checked temps but was that CPU or GPU? Can you take the case apart enough to check that all that fans are spinning freely while it renders? If they are but it looks dusty inside it might be worth a few squirts with some canned air.
The other thing could be a dodgy asset. Have you tested renders with completely different scenes? - i.e. with zero assets in common between them in order to rule that out. I am no expert on diagnosing error logs but the first failure being a MaterialSurface might indicate some texture/shader that is causing your setup issues so making sure to do some very distinct tests would help there.
When I checked temps it was on both the GPU and CPU and I did them with an open case actually. The dust before my spring cleaning was minimal but I still did it.
The MaterialSurface error is the first time I hear off. I know you mentioned that you aren't an expert in diagnostics but would you know of any kind of way for me to locate said dodgy asset? Cause I have a lot of assets downloaded and trying to figure out which one might be a hassle without any sort of direction to go on. Thank you for your input!
Well, downloaded assets wouldn't be the issue as iray would only be processing the materials actually present in the current scene. I also believe you are right to discount the "black screen relating to VRAM" since in that case the render actually "completes" with a 100% black render displayed in the window rather than the whole monitor display doing dark. You also get a different error relating to exceeding the ram and not being able to fallback to CPU which is not present in your error log.
The best way to check to see if this is the issue would be to open up some of your older scenes that used to work and re-render some of those. It seems like your current scene is causing the failure after 20 seconds and so it shouldn't take long to work out if the older scenes are fine. If those olders scenes also fail then it might be driver or hardware issues - or perhaps some software issue with Daz Studio. You can try switching out your nvidia driver - I know you said you updated to the latest version but sometimes the latest version has issues (although then there is usually other posts here about it). There are also two versions - gaming and studio so it might be that you need to try the other one. Also, you can try rendering your scene in either the Daz Studio Beta or 2025 Alpha to see if a different version of Daz Studio will work on the scene.
If the older renders still work then it's likely that there is some asset that is causing the problem. If that is the case then I unfortunately do not know of a "good" way to figure out what it is. There is the "divide and conquer" approach of removing half the items and then seeing if it renders, if fails then you know its one of those so remove half again and re-render, if any renders pass then the finger of blame can point to the ones you just removed so swap the assets around. Keep splitting things in half until you have only 1 product remaining that won't render even on it's own. Unfortunately, this method is far from ideal since not only are you having to force-reboot on every failure but it's quite time-consuming and only works if there is a product that causes an issue on it's own - if the issue is caused by a material interacting with a specific amount of light/shadow or whatever then you'll likely not trigger the failure after splitting up the scene. I don't know if it's possible to run Daz Studio with an extra parameter to output even more debugging logs.
I've tried with fresh scenes with no common assets but I will try and go back to some really old renders if the problem still persists then I think I can eliminate the asset theory. I also want to try an older version, more stable version of Daz3D but there is no way for me to get my hands on it officially from the Daz3D team. Been in contact with their support team about this aswell. So I'm kinda at a loss. I will try to see what happens when I go back to older scenes and get back to you as soon as I can.
You can try rendering with your CPU only... if it works, usually there shouldn't be an error from Daz assets.
In NVIDIA control panel, restore settings of Daz Studion.
Besides, have you recently installed or updated any packages of NVidia CUDA Kit ? If you have, uninstall them all and try again ~
