A long-standing issue that has been troubling me. - hijack - 07-25-2023

I have been plagued by an issue for over a year. I have a machine with 3x2080ti GPUs, and when hashcat starts working, I occasionally encounter the error "NvAPI_GPU_GetPerfPoliciesInfo(): NVAPI_NVIDIA_DEVICE_NOT_FOUND". The only solution is to force a power-off shutdown. I initially thought it might be a motherboard or GPU problem, but even with a brand new motherboard or GPU, the same error persists. I am seeking advice on how to resolve this issue. I humbly request everyone's assistance and I am immensely grateful!

Are you using PCIE risers?

Hello, I'm not using risers. The graphics cards are directly plugged into the PCIe interface.

According to 
https://docs.nvidia.com/gameworks/content/gameworkslibrary/coresdk/nvapi/group__nvapistatus.html

NVAPI_NVIDIA_DEVICE_NOT_FOUND
No NVIDIA display driver, or NVIDIA GPU driving a display, was found.

Have you tried removing the drivers and reinstalling them?
