I bought a nVidia 9800 GTX a few weeks ago. It would not fit in my old case, and I needed a new power supply.
I bought a new TX750 watt power supply. nVidia said that was powerful enough to power two of my video cards if I decide to SLI, which I have planned in the future.
I moved the motherboard and all to the new case and installed the new video card. The computer came on and everything looks fine.
My monitor is connected to my onboard video card right now. If I connect it to the 9800, the monitor doesn't come on. I attempted to install the 9800 driver (nVidia 266.58), but it said the "Install cannot continue. This graphics driver could not find compatible hardware."
The video card is on (lights on, fans running).
My old graphics card was a nVidia 7100GS if it matters.
What should I try next?

remove both cards and try booting with the on board video, install drivers from the website, then shut down and try one card at a time.Doing everything at once makes it difficult to isolate the problem.

have you removed the 9800 and put the old card back in?

@pachm: The old card has already been removed, and I am on onboard now. The problem is that I cannot install the driver. When I try to install it by running the file, it loads and gives the error message that it cannot find the hardwaree. It seems that if I remove the card, it will still tell me it cannot find the card, and not allow me to install it.
The 9800 gtx has two spots to connect to the power supply, a 2x3 and a 2x4. I connected both of these. Was that correct?

ok install one card, the system should detect new hardware, then choose the driver an install. if that works, install the second card and setup sli. I hope this helps you some.as for the connections i thought the 9800 gtx required 2 6 pin pcie but obviously if it has a 6 and 8 i am mistaken. so yes connect both.

Is the BIOS set to boot up off the PCI express lane first?

@pacham: I only have one video card, as my old one stopped working. So I do not have an SLI setup yet.

@patriot: I could not find anything about PCI express lane in BIOS.

A bit more info: Like I said, the video card is on, I can see the lights and here the fan running. If I plug my DVI cable into the 9800, my monitor will not come on.
When I run dxdiag, I only see my onboard video showing up.
Also, when I go to nVidia, I tried to auto-detect my drivers, and it doesn't find my 9800.

Also I realized I typed the wrong name for my video card. I actually have a GeForce 9800 GX2 XT.
On nVidia's driver's page, there is only a driver for GeForce 9800 GX2 (no XT).

DVI works fine onboard, but not on the 9800 (the monitor won't come on).
My old video card works fine in the PCI-e slot. Wouldn't that mean the motherboard is OK?

My board is an Asus M4A78 PRO, and unfortunately I don't have another PC to test it on.

Not sure yet.
I called a local computer repair store to ask them if I could bring the video card down there to see if they can pop it into one of their PC's and see if it would work, but they wanted to charge me $59 for a diagnostic service...
A friend suggested flashing my BIOS, so I am looking into that.

I think I would just RMA the video card and see if the replacement works.
