Precision 7720 Windows 10 with Intel and NVIDIA Quadro P3000 GPUs.

This NVIDIA card worked fine for years, but in the last 6 months constant BSOD with an NVIDIA error. Tried the latest and old drivers. None seem to eliminate the issue.

Latest problem is Photoshop won't recognize the P3000, only the Intel card. I've gone into System, Display, Settings and assigned Photoshop and other intensive programs to use the NVIDIA, but they won't. I've gone into the NVIDIA panel and for 3D settings done the same thing, assigned graphic intensive programs to the NVIDIA. No luck.

And just now when Photoshop was open an unable to recover from kernel error related to NVIDIA.

Any advice? Thanks.
