nVidia 8400 GS and ATI Radeon 9200

I have an older PC with two graphics cards installed; a Sparkle nVidia 8400GS (PCI, 512MB, DVI/HDMI/VGA) and an ATI Radeon 9200. (AGP, 128MB Analog/VGA) The 8400GS has been working perfectly, no problems whatsoever. The Radeon 9200 has *also* been working perfectly, but the thing is, I can't seem to get them to work at the same time. I've consulted the almighty Google many times over a couple of months and haven't been able to find an answer that works for me! I'm going to have two outputs from the 8400GS and one output from the Radeon 9200 when I'm done. (If I *am* ever done with this silly contraption.) I believe it worked perfectly on windows XP (too long ago for me to remember), but that's a whole different animal to deal with. I would really appreciate the help if anyone has any solutions! If there's anything else I can tell you, I would be glad to! Also, when I shut down while using the Radeon, I got a BSOD, but, as I understand, that seems to be a common problem. It's 4:00am where I am and I'd love to get to bed, but thank goodness for Thanksgiving break! Also, yes, I know the Radeon is way old, but it's all I have for now.

Yes they will. The problem is that he is trying to use a totally unsupported card (9200) on a barely supported interface (AGP), with a card that has full Windows 7 support (8400). It also comes down to the different driver models being used. The 9200 only has a XP driver (XPDM) where the 8400 uses the WDDM 1.1,

Windows Display Driver Model - Wikipedia, the free encyclopedia

and you'll likely find that the 9200 driver is canceling or causing the 8400 driver to not work (same thing would happen if you used that 9200 with any ATI card from the HD 2xxx series and up). The BSOD is likely caused by the AGP driver itself depending on which chipset is in that computer.

As for a fix, the only real fix would be another card that uses the WDDM 1.1 driver, wither AMD or Nvidia. Only thing with that is that any card you buy (unless you can find a really cheap used one) is that a new card costs more than the computer is worth.

I appreciate the quick reply and I guess I'll just give up on my dream of three monitors... for now... Oh, well. I appreciate the help and I'll cut my losses!
