Try running the DX tests and see if any errors crop up. Also, try changing the AGP aperture size in the BIOS. Check the temps on the motherboard and also check that the card is getting enough power. The FX5200 needs around 35 watts. From the issues you describe it sounds like it's underpowered under the stress of running Civ4 or you have a overheating component somewhere.
