Question about MSI RX1550-TD256E RADEON X1550, (256 MB) Graphic Card
Whenever I hook up the MSI ATI RADEON RX1550 TD128EH card I turn on my computer and my old Display Adapter is disabled and disappears from my Device Manager completely. I'm running Windows Vista Home Premium 32-bit on a new Compaq Desktop with a GeForce 6150SE nForce 430 chipset with integrated graphics. I want to use dual monitors by utilizing both the stock adapter and my new graphics card. If I turn off my computer, take out the MIS graphics card, restart, everything goes back to normal and works completely fine. It probably wan't smart but I plugged in the graphics card while it was on to see if it made any difference it didn't and the card still works. I have proper drivers for both Adapters and they both work independently from eachother just the built-in one disappears when I plug the new one in. Searching for new hardware, re-installing drivers, none of that helps.
You should be running the same make video card, because the same driver runs both of them.
