Gigabyte HD7850 on B75M-D3V

[kyleawolfe]

Cannot get card to send display signal. I'm running a B75M-D3V with G860 integrated graphics card. When the 6 pin power supply is connected to the new card, the integrated card shuts down and will not display anything as if it detects the new card. I bought a 600W power supply thinking that my 450w was not enough, same result.

After this I began forcing PEGO 3, 2 and 1, switching the priority to PEGO everytime.

Any idea whats going on here?

Are you sure that you have connected the cable to the dedicated GPU and not the integrated?
What about the power? Have you connected the power cable from the PSU?
Checked behind the screen if everything was connected?

My OP states that then the 6 pin power supply is connected to the new card, the integrated card shuts down. So yes I'm powering up the new card.

Yes I'm sure I'm connecting to the dedicated GPU... with all three monitors in fact... 1 DVI, 2 mini HDMI.

You can rule out monitor problems... Im using the same DVI to switch between the integrated and dedicated GPU when restarting to enter the BIOS
