I upgraded to the Asus Sabertooth 990FX R2.0 and the AMD FX4350 4 core black edition cpu. I have an Nvidia Quadro 4000 video card, 4 sticks of ram. A warning keeps popping up, "Warning vcore voltage 0.840 v" I haven't touched any of the bios settings. It started the first time I booted up and can't get it to go away, before I even started running any programs. Help me out please.
