I just purchased a new graphics card (Asus Nvidia en210) for a Dell Optiplex 320 Minitower so I could use two monitors on it. The card is the correct slot (PCI-E) and has the correct form factor for the minitower. When I start the computer with it in and the monitor plugged in to it the computer works, I get visuals and everything.
The problem is that the computer doesn't detect the graphics card. It doesn't get installed automatically and if I try to install in manually it doesn't find it. Its not listed under device manager and if I go to display adapter under settings it lists everything as "Unknown".
When I try to install the driver (the one with the disk, the one from the Asus site, or the one from the Nvidia site) it either says it can't detect the correct hardware and won't install the driver, or just skips the entire installation phase after the hardware detection phase and says that its complete even though it didn't install anything.
There is no old drivers to remove, the BIOS is set to use the add-in video card (obviously, since it is working on a basic level), and I've tried everything else I can think of.
FYI - I need the driver because while it works without it its very poor, windows update in a choppy fashion and such.
