added video card, but now no display on monitor

Hi All,
I added an ATI Radeon HD 4550 video card to my desktop. It already has a perfectly working built-in card, but I wanted DVI for my new monitor. I thought I downloaded and installed drivers before installing card, but now when I turn on monitor it starts up but screen goes black after "starting windows" displays. I still have old and new cards installed. Old card is VGA. Any help would be appreciated. Thanks.

Is the old card onboard?  If so, disable it in the BIOS.

Configure BIOS video options and set "Primary Graphics Adapter = PCI Express" and not integrated adapter.

I don't see those options. I see "Onboard Devices" or "PCI Devices" in BIOS.

It's just strange that both video cards are plugged in and monitor has duel vga/dvi output but won't display either when both are installed.

Under Onboard Devices do you not have VGA or something similar?

Under PCI devices it lists Intel VGA controller IRQ 5. Should i disable?

Have you tried connecting the monitor to the onboard display adapter port? If you get a working display, you will have to disable the onboard adapter.

What computer do you have? Sometimes the BIOS options are neither clear nor logical...

If you highlight Onboard Devices in the BIOS and press Enter, that should take you to a submenu in which you can disable the integrated graphics adapter.

If i disable it in bios will it still allow me to change it back if needed?

Yes you can re-enable it later.

I only have it plugged into new card through DVI and it starts up and displays up to the Starting Windows screen. I do not have VGA plugged into on-board card. That is not a driver issue, but a BIOS issue?

The only Onboard Devices listed in BIOS are Serial Port A or Parallel Port. I only see option for VGA in PCI devices in BIOS.

What is probably happening is that Windows is trying to display through the onboard card and not the DVI card.  If you disable the onboard card, Windows will then use the DVI card.

Correction, now that I only have DVI plugged into monitor and no more VGA, it no longer lists VGA option in BIOS. I'm starting to think this is a driver issue. . . since BIOS doesn't display VGA when I plug into new card.

It's a driver issue. I was able to remotely connect to computer and it isn't recognizing the device. I must have downloaded the incorrect driver.

Does your new monitor have VGA on it as well? If so, try using the VGA interface on your new card. I've found that sometimes Windows looks for the VGA interface when it's starting up, rather than the DVI one. The fact that the Windows splash screen displays until the display mode switches to graphical suggests that this is what's happening.

Did you use the drivers on the CD that came with the card? If so, you may well find that newer drivers are availble from AMD's site. I generally don't bother with the bundled drivers for graphics cards in machines that aren't used for serious gaming, but go straight to the graphics chip manufacturer's site for the latest ones.

It turned out to be a driver issue. None of the experts had be troubleshoot driver issue. I was able to resolve it on my own.
