Hi everyone,
I've been working on this for a few days. Here are the basic symptoms:
When I install the nVidia gforce drivers and reboot the system the driver prompts me saying that the system is SLI capable and do I want to enable it. Naturally, I choose yes. The driver dialog box is brought up and I can check the SLI checkbox. Doing so brings up a reboot dialog so I let it reboot my system. Once the system comes back up I am in standard VGA mode with no nVidia drivers loaded. I know this because the task bar try icon isn't there and going into advanced display settings shows that there is no nVidia menu.
I've done quite a few things to try to fix this. Initially, I was forced to update the bios because the SLI tab only had the EZ Connector warning on it. Rebooting forced me to remove one card because the new bios was defaulted to forced single board mode. After setting SLI to Auto and SLI Aperture to Auto, I reinstalled the second card, flipped the selector card, put the connector on the two cards and powered up the system.
I installed the nVidia drivers that came with the video card and then windows blue screened. I lost my USB keyboard and was forced to connect a normal keyboard to the motherboard. I then downloaded the latest nVidia drivers from Asus' site and installed those in safe mode. This allowed windows to boot and gave me back my USB keyboard. Then I started having the problem I'm having now. Enabling SLI in windows and rebooting causes nVidia drivers to disappear.
I've uninstalled and reinstalled in every possible configuration. Using both nVidia drivers from nVidia's website and Asus' website. I've installed latest and greatest nForce4 chipset drivers. I've pulled out the video cards and tested both in single board mode.
I was on the phone with Asus' level2 support guy for about an hour. He was completely stumped and left me with the standard RMA the motherboard line. I really would rather not do that since I have a feeling the motherboard doesn't have a problem.
And so I turn to the gurus here in the hope that one amongst you has had a similar issue and knows how to fix it. Listed below are my system components.
