Pascal, thank you for your input. There are no options in my BIOS for disabling graphics, so I can't do that. As for HDMI, I don't use an external monitor for editing. I don't yet know if my use of HDMI will be affected, it's a minor concern anyway. Right now I only hope that someone with specific knowledge of the phrase '[opencl_init] could not get platforms: -1001' will comment. Meanwhile I continue my research.
