Did this latest set of drivers install without you forcing them?
Those instructions are basically right, but in nvam.inf there are 4 560m's; 2 go to one section, and 2 to another. I don't know what those differences are. There could be something that causes problems if modded the wrong way.
%NVIDIA_DEV.1251.01% = Section066, PCI\VEN_10DE&DEV_1251&SUBSYS_13B71043
%NVIDIA_DEV.1251.02% = Section066, PCI\VEN_10DE&DEV_1251&SUBSYS_204A1043
%NVIDIA_DEV.1251.03% = Section085, PCI\VEN_10DE&DEV_1251&SUBSYS_204B1043
%NVIDIA_DEV.1251.04% = Section085, PCI\VEN_10DE&DEV_1251&SUBSYS_21001043
Luckily, they installed to my laptop unmodded.
