It may be attempting to load both cards so you'll need to disable the onboard card in Device Manager.. And it's also possible you need to update the driver on the new card to the newest version.
Open Device Manager, then click on the + sign next to "Display Adapters", then RIGHT click on the onboard card's device name, choose "Properties". At the bottom of the page, in the "Device Usage" line, use the drop-down arrow to select "Do not use this device (disable)", then "Apply" and OK your way out..
Once that's done, download and install the latest driver for your ATI card.
Restarting the computer should allow the new card to be recognized as the only graphics card.
Hope this helps.
I'm having an issue with a Video card driver in Windows XP Pro. I recently did a repair install on the computer because the internal video adapter went corrupt and was causing a BSoD. It took awhile to finally get past that part on the repair install of Windows and I installed a new video card in the computer to use as the default video card. The video card that was installed was an ATI Radeon 7500.
Once Windows came back up it would have a yellow mark by the video card in the Device Manager. I ran the update from the ATI website that corresponded to the Video and it said everything installed correctly, but when I restarted the computer it still had a yellow mark by the video card and it was saying that it couldn't start this driver or that it was corrupt.
The only way I can get it to work is if I uninstall the driver and then have windows scan for a hardware change and re-install the driver through windows. Once it is done everything works fine, there is no yellow mark by the video card in the Device Manager.
Once I restart the computer though, it reverts back to how it was before, stating that the driver is corrupt or it can't start the driver.
It is driving me nuts any help would be appreciated.
