I had this system for almost two years, with 2 4090s running smoothly. I started to have random crashes, like the fans on the cpu going at full speed and the screen going blank. So I updated the bios, first time since I have the system, and since then my second gpu is sometimes recognise and sometimes not. And when it does I try rendering in cinema 4d and it doesn’t show up or it doesn’t render. I have the system working with 1 gpu and it all works ok. But I want to get both back online, I tried the second gpu on another computer and works perfectly.
