I have a dual boot system with Win XP on one partition and Vista 64 Ultimate on the second partition. Sometime recently, perhaps at the latest Windows Update on Vista, my nVidia Control Panel stopped working in Vista 64. I am using nVidia driver
185.85, the latest non-beta version available. I am using nVidia system tools 6.05, the latest set available. I have cleaned out my drivers
with Driver Sweeper, and reloaded them with no change. I have loaded the drivers with all virus software shut down, with all unnecessary apps shut down. When I try to start up the nVidia control panel, whether in the Windows Control Panel or other shortcut, Vista tells me that "nVidia Control Panel has stopped working". I am getting the impression that the nVidia drivers are not running, since when I add them they are not defaulting to max resolution like they normally do. The system seems to be running on some default video driver instead.
CPU, GPU, MCP temperatures are nominal, no indications of problems there.
I would greatly appreciate some advice on how to trouble shoot this and get back to working properly.
My system specs are as follows:

When Vista tells me that nVidia Cont. Panel is not working it tells me the following info on the failure. I wish I knew how to interpret this.
