New findings. GPU-z wasn't showing the second video card, even though the fans were spinning like they should. I tore the machine down and verified that it was indeed dead.
Not being able to find another R9-290X Locally I bought two new R9-380x cards and put the 290x into spare,
Cleaning out all of the drivers and installing the new ones didn't help. GPU-z sees both cards, and radeon settings will not start. I have tried the drivers that came with the card, and when using those both cards worked and all 6 monitors function. Launching a game hangs the machine on that release.
When I attempt to use 16.3.2 or 16.4.1 Radeon settings does not come up on the dock, but it is available through start menu but does not launch.
I'm pretty much out of ideas. Any help is greatly appreciated. I'm about to take these things out and go with nvidia.
