I am successfully displaying Windows 7 using the integrated Intel GPU. I made sure that in the BIOS of my ASROCK H67M board I set the integrated graphics as enabled/primary and support multiple displays. Meanwhile I have a GT710 card running and developing CUDA code on it.
My question is, when I compute (CUDA on the GEFORCE card), Windows 7 flashes, goes dark and gives me a “Graphics Not Responding” warning.
Does anybody understand the innards of how Windows graphics works and why it cares what’s happening on the NVIDIA chip? It seems like there is still a shared frame buffer or bus or something - but I’ve read through many posts and it seems that nobody really explains why we can’t cleanly isolate multiple GPUs in a Windows computing system???
