My PC restarted right before my render could finish

My PC restarted itself for absolutely no reason…It had a few hundred more samples to go and I was rendering for about maybe 3 hours and it was nearly finished. I was zooming in and out of the render to check out the quality and all of a sudden my screen went black and restarted. I didn’t have any windows updates available. If I did, I would be the one to decide whether to update or just skip and shutdown.

Just thought I’d bring this up as this never ever happened to me before.

  • Rendering a 4K image with cycles, running Windows 10 i9 core with Nvidia GPU.
    I don’t know if this will happen again but, I will need to start my rendering again.

I wonder if you ran out of RAM…

( There is no such thing as: for absolutely no reason :wink: )
Overheating ?? Power supply outage because of this? Even BlenderGuru blow up a Rendercomputer some years back this way… so you may be lucky…
