I recently put in a new video card. I went from an nVidia to an ATI. After the installation of the new card and software, I uninstalled the nVidia drivers and software via Add/Remove Programs. Now everytime I boot the computer I get two error messages: "Error Loading C:\WINNT\System32\NVMCTRAY.DLL" and "Error Loading C:\WINNT\System32\NvCpl.DLL." I can guess that scvhost.exe or other such process is trying to load these .DLLs but not finding them. How do I tell whatever is looking for them not to anymore?
