When I sent my PC in to the manufacturers, the NVIDIA control panel worked fine. When I got it back, it didn’t work. I forgot about it for a while (no real need to access it, everything else was working), and when I checked it again it was working, but I never figured out what the cause and solution was.

Well, I installed multiple monitors yesterday and today I’m having the same problem again. After Googling around, I came across this useful article that turned out to have the solution:

  1.  Start > Control Panel > System & Security > Administrative Tools > Computer Management > Services & Applications > Services
    Start > Run > services.msc
  2. Find NVIDIA Display Driver Service.
  3. Stop service.
  4. NVIDIA Control Panel may display if you previously tried to access it. If so, close the NVIDIA Control Panel.
  5. Start the NVIDIA Display Driver Service
  6. Right-click on the desktop, select NVIDIA Control Panel
  7. NVIDIA Control Panel will open
