I have a Dell Dimension E520 PC (4 years old now) and for a long time I've had a dual monitor set up using a Sapphire Radeon HD3600 series dual-DVI video card.
I'm running Windows 7 64-bit.
Recently I purchased a PCI (not PCI-E) graphics card, which happens to be an ATI 7000 Series card (quite old). I slotted into my PC and booted up, after which Windows 7 showed it in device manager as Standard VGA Adapter, but on the display properties I couldn't see any monitors attached to it.
I went into the BIOS and chose the PCI card as the on-boot video card, and Windows proceeded to boot ON THAT CARD ONLY. When I look at display properties it now only lists the single PCI video card, but in device manager it lists both cards.
Now I've booted back with the PCI-E card selected in the BIOS, and same problem, except this time the Standard VGA Graphics Adapter is appearing in Device Manager with an error - "This device cannot start (Code 10)".
Any ideas what on earth is going on? My end goal is a three monitor set up.
