Solution that worked for me:

  1. Start Task Manager
  2. Find GFExperience.exe *32
  3. End Process
  4. Re-launch GeForce Experience from system tray
  5. Installation completes successfully

This also seems to have fixed a problem with games not optimizing. I’d been putting off reinstalling drives from scratch (clean install) so this is a nice bonus.

Straight from the README for the latest NVIDIA drivers. Going to give this a try next week when I have more personal time.

Increasing 4-way SLI/Multi-GPU Performance


With some games and applications, you may experience little to no performance gain or
even a performance drop with 4-way SLI or multi-GPU configurations.


  1. Open the NVIDIA Control Panel, then click Manage 3D Settings from the navigation
  2. Click the Global Settings tab, then scroll to the Power management mode feature, click the corresponding list arrow and select Prefer maximum performance, then aclick Apply.

Playing around with my multi-monitor setup caused the multi-GPU (SLI) setting to disable. It all started when I was exploring whether it was possible to span a game across multiple monitors.

I have Dual-EVGA 590 GTX HydroCopper video adapters (which is effectively a quad-GPU setup). I’m running NVIDIA driver version 301.42 with DirectX 11. My motherboard is an ASUS Maximus IV Extreme with a Intel Core i7 2600K CPU (Sandy Bridge).

I selected NVIDIA Control Panel > Configure Multi-GPU, Surround, Phys-X > Span displays with Surround

It accepted the change, and then when I tried to run several games it didn’t work. (The reason is because my 3rd monitor is not the same size as all the others, which is an obvious requirement, but one I wasn’t aware of until I started researching that problem.)

When I changed back to Maximize 3D Performance, the computer BSOD (Blue Screen of Death) and my multi-hour recovery process began.

After figuring out how to uninstall the drivers cleanly, re-install, I was able to re-enable Multi-GPU support (so long as I only had a single monitor connected). As soon as I connected a second or third monitor, the computer would bluescreen. The fact that it happens on-demand means I should be able to get ahold of EVGA support and get them to diagnose the problem.

So, for now, if I want multi-monitor, I have to disable Multi-GPU support, then connect the monitors.

If I want Multi-GPU support, I have to disconnect all the monitors, then enable Multi-GPU.

Multi-GPU with multiple monitors results in BSOD.

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
