Windows can't tell which is onboard & PCI-X

I've got a pecular problem. I am building a media center out of an old HP, I installed a new video card (MSI R4350-MD512H), and I had everything working fine under Vista Home premium. I recently upgraded to Win7 Professional (custom upgrade) and this happened:

Windows cannot see the PCI-Ex16 graphics card, only the default display adaptor will appear in the device manager. I reinstalled the drivers, but nothing happened.

To see what would happen I went into the BIOS, changed the video from PCI-Ex16 to onboard, plugged the monitor into the onboard VGA port, and restarted. Amazingly now windows can see (and think's it is using) the new video card.

Video only comes out of the card set in the bios.

Any suggestions, is there something I'm missing? You can seem my other system specs in my profile

If device manager is showing "standard VGA" for your video card, that just means it hasn't loaded the drivers and is using the basic windows default drivers. It doesn't necessarily mean its using the onboard video, it just doesn't know what your actual video card is. Hope that helps.

Did you change the graphics settings in the BIOS?

figured it out

I got it working, I had to manually install the driver (using the "have disk" button), and found the card in the list.

Incidentally, I figured out why it was seeing a graphics card when it was plugged into the motherboard. I forgot that NVIDIA made the onboard and it was detected as an NVIDIA card. I saw an NVIDIA card and assumed it was detecting my PCI-EX card.
