The following works on my system, but bear in mind I have Windows XP and an A7A266E motherboard so it might not work for you. Also, you undertake this at your responsibility. It's a simple process, but you might want to backup before you do so. Up to you.

1) Install RivaTuner (http://www.guru3d.com/rivatuner/) if you haven't already and then run it.

2) Click on `Power User' tab and ok the warning that appears about it involving registry editing.

3) At the bottom of the RivaTuner window there should be a toolbar. Click on `Open Matched Detonator Database' which should be 2nd from left.

4) Then click on the plus before `nVidia Detonator xx.xx wxx System' (so for me it reads `nVidia Detonator 44.03 w2k System'.)

5) In the menu that branches out below there should be an option that says `Enable x AGP' (so for me it reads `Enable ALi AGP'.) Right click on it and click on the yellow lightbulb.

6) Click ok and reboot. It should now work. Hope it does.

Sorry to hear it didn't work. I hope someone else can help you out, as I don't know what else to suggest.

You will need to down load agp driver's for your motherboard. I think that might be it. Go to the drivers site of the maker of your mother board look
at the drivers page it should have some kind of agp drivers on it install them then the tab should show up in directx. Good luck you will see a big speed boast.
