Never had that kinds of troubles with installing a new video card

[abaris]

I recently bought a new rig, having an Asus F2A85-M Pro motherboard and it features an onboard card. It also has two PCIe slots and I installed my card in one of them. The one that's actually designed for it, which I had to learn the hard way, since the other one is only there to rund two cards. But when starting the rig, the monitor stays black, since it still considers the onboard device the primary source. At least that's my assumption.

So, do I have to deactivate the onboard device in BIOS before trying to start with the new card? I'm rather reluctant to do that out of fear that I can't run neither afterwards.

Never had that kinds of problems. It was always plug, install drivers and go.

Are you familiar with tweaking the bios? Disabling the onboard vid should be the first thing you do if you install a dedicated graphics card.

Yes, I am. Problem is, if I deactivate onboard and it still doesn't recognize the new one, I'm sitting before a black screen without any possibility to roll back.

You can always reset the bios if so

Are you positive the card is compatible! double check. wasn't there a voltage change in the pcie standard a while ago?
Also put in any other card in the same slot to confirm the mb port is ok.
If the mb is ok, reset or pull the battery out temporarily.
last resort, put new card in another pc to confirm... Something may be doa!

Are connecting on vga, dvi or hdmi? Have you tried changing? Maybe it is working but not on that output? just a thought.
If you are using 2 monitors, turn one off and unplug it from the card.

Process of elimination.

Yes, it's compatible. I mistakenly put it in the wrong PCIe slot, the one for running 2 paralell cards, and it fired up, although crashing windows in the process. It also shows up in the hardware monitor as a VGA device.

What os are you running? 32 or 64?
Is this a brand new mb?

I'm running Win7 64 bit. I bought this rig new, but it's about 2 years old. That's why it was on sale at an online vendor. Same with the card, which isn't an incredibly powerful model anyway. It's a Geforce GTX 650ti, but it's a DX 11 card.
