Windows 10 Black Screen

in Technical Help (nuts n bolts)

I'm hoping someone here can help me out. I was on Windows 7 and in the past month or so, Daz was getting laggy to the point where I could barely navigate the smart content pane. Since there were some other lag issues not related to Daz, I upgraded to Windows 10 to try to resolve it.

Daz ran a little better, but not great. I changed my interface optimization from none to best and now there's no lag in nagivation/panning/etc. It's smoother than when I first installed it. There's still lag when adding a new prop (sometimes as much as 10 minutes before the "not responding" message goes away.)

I've noticed that the memory manager tends to shift RAM from Daz to System even while I'm using Daz. My total used RAM never goes above 68%, so it seems like it's making the shift because it thinks Daz is idle. I could be wrong.

Last night I tried to render an image using Iray and after about 2 minutes, my screen goes black and won't come back on. I let the render run over night (max render time is 2 hours) but the screen still won't come back on. It takes a hard reboot to resolve the issue. I've tried a couple of times since this morning and I get the same results.

Most talk online points to video card driver problems. So I've updated all of my drivers. I uninstalled my video drivers, restarted, then reinstalled the drivers, then restarted, but I still have the issue. I've tried installing the drivers from Microsoft and I still have the issue. I've tried installing the drivers from NVidia and I still have the issue.

I know I'm running an older system, but I didn't have this issue with Windows 7. I waited to go to 10 so MS could (theoretically) work out the issues in their initial release.

Does anyone know how to resolve this?

Thanks.

    If you only have 1 GB of video card memory, then it isn't very likely that Iray is actually using that to render, especially if that video card is driving your monitor, too.   So most likely what is happening is that there is a problem when Iray fallsback to CPU rendering.

    Try switching to CPU only in the Iray settings (I think it is Render Settings > Advanced).

    I know the video card doesn't support GPU rendering. I'm fine with CPU only rendering, and I never had any problems on Windows 7 (other than longer renders.)

    The video card was unchecked by default in the render settings. I tried it both with and without including the GPU and I still have the same problem.

    As I'm doing more testing, I've found that a simple scene (1 figure, no props, 4 lights) renders without a problem in both 3Delight and Iray. So the problem seems to be when dealing with more complex scenes. I'm still wondering if it has something with the new memory manager in Windows 10.

    I also noticed that my Iray content isn't coming up in the Smart Content pane anymore. I had several light sets, mats, etc. in there and they're all gone now. I can still access the Iray shaders from the Shader pane. As far as I can tell, all other smart content is there.

    It looks like my problem was not enough RAM. Going through former scenes, I was able to get them to render without a problem. I guess the scene I had was too big, and Windows freaked when it tried, even though as far as I can tell my memory usage never got above 68%. I'm still not sure why it would kill my screen.

    I ordered more RAM (and a new motherboard and CPU) a few days ago and they arrived today. After getting everything switched out and back up and running, I'm able to render the scene without an issue. It's sitting at about 12.5 GB used for Daz. There's no weird memory manager behavior and nothing else is acting weird.
