Lets start over..
You might find all the info you need in your computer manual. Or you could just call Dell and ask what your computer's motherboard supports.
If not, you might download this program http://www.pcpro.co.uk/?domain=custompc ... nload.html
and after the install
Expand the- motherboard tree.
Read- motherboard name.
You can then Google or go to Dell's website and find out what video cards your motherboard supports. For example, AGP 2X, 4X, 8X...

Here's the list of recommended video cards and drivers- http://support.lucasarts.com/tsg/SWBFQu ... tedVCL.htm
To replace the video card, assuming you have an AGP slot.
Turn off the computer and unplug the power.
Press the start button to discharge the computer.
Be careful of static charges from your body.
Remove the case cover and look for the AGP slot. Start by looking at the bottom of the motherboard and raise your line of sight. You will see a series of horizontal slots, it should be the top slot above the PCI slots.
Remove the screw holding in the existing card. Look to the rear of the card to see if there is a retaining clip. If there is, release the clip and gently wiggle the card out of the slot.
Install the new card and reverse the steps above.
Start the computer, XP Home will install basic drivers for the video card. You then install the drivers that came with the card or use the updated drivers on the video card manufactures website.
If your computer doesn't post, shut down and repeat the steps above. Make certain the video card is fully seated in the slot.
That's what works for me, do so at your own risk.
PS, If you decide to go with a modern video card like ATI's 9800 Pro make sure that the computers power supply is large enough.
