Hello, I have a SB i5 with the dGPU. everything seemed to be working well until I checked the device manager and noticed that the nVidia GPU was error disabled (code 43). I have worked on it for several hours uninstalled, reinstalling drivers, installing updated modded drivers, uninstalled and reinstalling through windows update ETC. every time I get the same result. I am at the point of trying contacting Microsoft for a replacement, but I thought I would ask here if anyone has had a similar issue and if it was solved.
