Hi, I have an Asrock motherboard 960GC-GS FX, also I have a video card EVGA Geforce 8400GS 1GB for pci express. The video card signal gives me trouble, what happens is that the embedded video is not totally disabled and steals my system ram space, even though the integrated video signal does not give me is stealing ram. What could be the problem and how can I completely disable the embedded video not to steal me more ram?

PS: The version of the bios I have is the P1.30.

Thanks for your attention.
