Issues running dual video cards (PCI/PCI-E)

I've got a bit of a strange issue that I haven't had with previous OSes on this PC. I'm running a Dell OptiPlex 380 with Win 8 x64 at the office and I have to run 2 video cards for all of my screens. I have a GeForce 8400GS in the PCI-E slot and a GeForce 6200 in the PCI slot.

Previous to the Win 8 install, it worked fine. Booted exactly as I had shut it off. Now, with 8 - it's killing my PCI-E card presumably when it puts the screens to sleep when I leave for the day. So I'm coming in to all of my windows being moved to the PCI card's monitor (only one hooked to it) and I have to reboot to get PCI-E card to come back.

If I check the screen properties, I see only the screen hooked to the PCI card. I've changed the setting in the BIOS for the first video card to Auto and also tried the PCI-E selection and it's the same either way.

Why on earth would it default to the PCI card rather than the PCI-E card? Any thoughts?

Okay, so with everything working -- I rebooted just to see how it acts and it came back up with all screens / cards working. However I do see an exclamation icon on the 6200 PCI card. It says Windows has stopped the device, but the screen is working fine. LOL -- that's a new one for me. I've never seen a stopped device that still works. =)

I went and installed the drivers from GeForce and now I see "NVidia GeForce 6200" and "NVidia GeForce 8400GS" instead of the Microsoft drivers, but I still have the exclamation mark on the 6200. I still have video on that card though.

When I open the NVidia control panel, it appears that it's only seeing the 8400. When I click on System Information it doesn't show the 6200 at all.

Hello Corbryant, which driver version did you install from Nvidia? I have went through Nvidia's website and found this driver which was provided upon the launch of Windows 8 and seems to support both Geforce 6 and Geforce 8 series. Download and install this driver and see if it notices both of your gpu's. The Geforce 6200 is an old legacy gpu and it may not work with the latest drivers. Hope I have helped solve your issue .
