Windows 7 Running with SLI

[Jobbers]

I have Windows 7 Home Premium x64 and everything runs smoothly.
However, I have two NVIDIA GeForce Go 7950 GTX video cards.
Currently, only one is running.
Here's the problem.
When I try to enable SLI, after the restart, the login screen comes up with a blank, solid black screen.
The Windows logo shows up during the boot process, and when it gets to the point where the login screen should show up, the music still plays.
Once my computer gets into this mode, I can't switch SLI off, and end up needing to run it in safe mode, uninstall the drivers, and then install them again.

I've got the most current drivers, and I'm not sure what to do.
Searching around on the internet has given me no help.

It sounds like you're facing issues with enabling SLI on your Windows 7 system with two NVIDIA GeForce Go 7950 GTX video cards. Let's troubleshoot this step by step: 1. SLI Compatibility: Ensure that your NVIDIA GeForce Go 7950 GTX video cards support SLI and are compatible with your system. 2. Driver Clean Installation: - Start by completely uninstalling your current NVIDIA drivers. You can use Display Driver Uninstaller (DDU) in Safe Mode to remove all traces of the existing drivers. - After uninstalling, restart your system and install the latest NVIDIA drivers for your video cards. 3. BIOS Settings: - Check your system's BIOS settings to ensure that SLI is enabled if there's an option for it. - Make sure that all required settings are configured correctly for multiple GPUs. 4. SLI Bridge Connection: - Ensure that the SLI bridge is properly connected between the two video cards. A faulty or improperly connected SLI bridge can cause display issues. 5. Update Windows 7: - Make sure that your Windows 7 system is up to date with all the latest updates. Some updates may be necessary for SLI functionality to work smoothly. 6. Monitor Event Viewer: - Check the Event Viewer in Windows for any error messages related to the black screen issue. This may provide more specific details on what is causing the problem. 7. Test Each Video Card: - Try running the system with each video card individually to ensure that both cards are functioning properly. 8. Alternative SLI Settings: - If enabling SLI through the NVIDIA Control Panel is causing issues, you can try enabling SLI through the BIOS settings or using third-party utilities. If you continue to experience issues after following these steps, it may be beneficial to reach out to NVIDIA support or consult with a professional technician for further assistance. SLI configurations can sometimes be finicky, and expert guidance may be necessary to resolve the problem.
