Hi @ron9
First thing to do is to run the SystemInfo command in Rhino and copy/paste the result here - that’ll hopefully give an indication of what might be happening. A qualified guess would be to make sure that both your Windows installation and graphics drivers are up-to-date.

I have placed extra memory, 32GB, along with the 16Gb that was already in it.
But only 32GB was seen.
I have removed the extra memory and reinstalled it.
Now the laptop sees the full memory, and Rhino no longer crashes.
