Just added a third video card and 1200w PSU to my rig. The card shows up as "windows generic display adapter" (or some verbage similar to that. I wiped the Nvidia drivers and re-installed the latest release. The card still doesn't work (says it needs driver update, when you try to update - it says it is already up to date.) When the PC reboots after the driver update, it shuts off video display after the Windows 8 splash screen. I have to power off and restart. After the third restart, it goes into windows repair mode. It tries to roll back to a previous version and then cannot complete the task. I continue to Windows and it goes all the way through. The card still doesn't show and SLI settings are reverted to defaults and not saved. Are there BIOS settings for 3 way SLI that need to be changed in the card or MOBO? It worked fine with 2 way. Do I need to update a driver for the PCI controller? Clear CMOS? Any help or ideas appreciated. Hoping to not have to do a re-install of Windows 8.

Turns out one of the pci-e 6 pin modular cables had a short in it. May end up replacing the power supply anyway, as it was recommended to go higher to allow some headroom.
