The option to disable the onboard graphics is in the BIOS.
You need a PCI-express card. You should not be trying to fit any graphics cards into the PCI slot.
The VGA/HDTV conection should have been supplied on a seperate card.

Try removing the video card, and look up your motherboard / system manual on dell's website on how to manually reset the bios.
1. Remove video card 2. Reset BIOS (physically opening the computer and using a special jumper and/or removing the battery...what ever the manufacturer says to do to reset the BIOS). 3. After BIOS is reset, try booting up via your onboard video card first. Once you get that working, go into the bios settings and make sure it is set to boot the onboard only for right now and then you can make sure the ATI software is fully uninstalled when you get into windows. 4. Reinstall the ATI card and boot up with the video still connected to the onboard card. See if it will let you install the driver.
The trick here is to reset the bios and get the system booting off the onboard card if at all possible. If that works, then you can always reinstall drivers and then tweak the bios to boot off the AGP card instead of the onboard.
I beleive that your onboard is pretty much the equivelent to the geforce card you have spec-wise. But the 3300 a much new technology and has a faster processing speed in comparison to the geforce 6600 (not sure about the 7200).
In anycase, if you get yourself another ATI HD card (2400, 3450, or 3470) you can actually run them both as a Crossfire set up. Also, you can slight overclock your onboard video just a tad if that is a route you wanted to take.
The HD 3300 onboard was meant to be a better option over more entry level cards on the market today.
If you're still not sure, you can always do a 3dmark or gaming FPS test on each gpu to see which gives you the best outcomes.
For user BIOS21 & julio1963,
How to enable you're (Add-in AGP video card) & disable the onboard, integrated S3 graphics UniChrome 2D/3D PCI graphics card.
Enter you're bios. Open you're user manual to page 3-13. Integrated Peripherals. Go to, Init display first. Set to AGP.
(Not to PCI). That is all you need to change. The MSI bios will than see you're add in AGP card & automatically disable the PCI S3 graphics, (Onboard) card.
If I can help you further, feel free to post here.
Please, each user's vote this issue as a fix, if this helped you to get you're bios to see you're new AGP graphics cards.
