What a mess.  I removed a GEForce graphics card from a Dell Optiplex 320 tower.  I installed it a while ago for a dual monitor setup for a user & think it may be a bad card.

After I removed it, I plugged the monitor back into the built-in monitor (blue) connection/port.  (Original graphics card built into motherboard.)

When I turn the user's computer on, I get this message:

"No ATI graphics driver is installed, or the ATI driver is not functioning properly.  Please install the ATI driver appropriate for your ATI hardware."

Also, the screen started up completely black & now flickers.

When I look at Device Mgr for display, it says "ATI Radeon Express 1100".  (I'm not sure if this was related to the GEForce card that I just removed)

Before I installed the GEForce card, I believe the display was "Radeon 7000 Express".  (I'm wondering if that's what is built into the motherboard?)

Basically, I don't know what I'm doing and just need to get back to a functioning screen (and I'll deal with the dual graphics card later, whether it needs to be thrown/returned).
