Troubleshooting Dual Graphic Card Installation

[martex]

I'm trying to setup a dual graphic card system, using an HD 6750 as GUI and a GTX 650 TI 448 Core for GPU.

The nvidia card was already installed as the primary card on my system so I've download the latest driver/software from XFX for the ATI card installation. At restart, after installation, I got a "MOM.exe Framework Initialization Error".

I decide to uninstall all Nvidia and AMD drivers.

I was counting on the z68x-ud3h-b3 hdmi port as my last resource but definitely something went wrong and now I lost the video output signal. I tried every hdmi port, both graphic cards and the motherboard but I have no video output at all.

How can I resolve the issue and setup the system the way I mention? GTX 560 TI for GPU and HD 6570 as GUI. Which steps should I follow?

cheers,

Marta

Your first driver issue sounds like a .net4 error you can download amds driver with .net4 or get it from ms.

Wipe the bios of the mobo that should allow it to boot to onboard gfx , try and get into safemode with networks and reinstall both gfx drivers.

Ive only ever had issues multi carding (3cards 2vendor) when ive tried swapping pciex slots and it could be worth trying one card in slot 1 alone
