This was being built to support 12 monitors, due to the way the motherboard sits in the computer and the slots on the back for the out puts it won't accommodate three dual slot cards but that isn't the issue.

I built the computer with one video card and everything is running flawlessly. All devices were registered and functioning properly. I installed video drivers and updated everything except the BIOs.

---Here is the issue. I put in the second video card into the second PCIe slot. When I start the computer up and go to device manager, the second video card is being picked up and registered correctly and listed. The problem is instead of functioning it has one of those "yellow triangles with a !" on the name when you see it in device manager. When you then right click and go to properties there is this explanation **"Device Status - Windows has stopped this device because it has reported problems. (Code 43)"**. Its being picked up fine it seems when you look at the properties "Location: PCI Slot 2 (PCI bus 2, device 0, function 0).

I have exhausted all my ideas and in desperate need of help fixing this problem. I am *NOT* trying to run these two cards in SLI, I am simply just wanting to run multiple video cards for multiple outputs (these have 4 each).

---I tried all ideas, I made sure to redownload the video drivers and install them and no fix. I then tried to completely uninstall the video drivers and reinstall them and no fix. I then updated the motherboard from version "F4" to the most recent "F6" and no fix. I then in last attempt took out the brand new third video card that wasn't going to fit and replaced the second one with it incase it was a mechanical failure even though the fans spinned as they should and of course no fix.

I am still getting this vague error "Code 43" in device manager. Is there some simple thing I may be mixing in getting the second video card to work? To my understanding I thought it was just a simple plug the video card in the PCI slot and play since I wasn't going to use SLI, not the video card could if I wanted to (not supported).

Please help,
Thank you.
