Its very likely you have hit the memory management problem - a known issue in Civ IV.
There is a User patch that addresses this, has not worked for all, but has worked for the majority of people who have had the slow game - slow turns - slow saves - increased CTDs in the late game (typicaly starting from around the 1700 / 1800s). There could be other things causing this (so keep expectations on the level), but as you are apparently stable - as such - in the early game, you look to be a classic for this fix, and its worth trying this first as its easy to install / deinstall. As of this morning the thread dealing with the fix has had 116,000 hits at time of this post, with lots of endorsements there. It does not touch game code, nor mess with your PC setup, so you can consider it a benign Patch that is in any case easy to deinstall if you dont want it in the end.

Post 1 shows you how to install - its an easy unzip, copy and run it. The default settings (there are 2 that you can change ) get most up and running, but its very very worthwhile optimising the values of the settings to get best results. Have a look at the thread and you will get the idea. The guys on the thread are v helpful, so ask if you have concerns / confused / want advice on the settings.

Its new Nvidia drivers that may be of help with other less drastic problems you have.
We all hope it will not be long before the next Offcial Patch - some news on that is at:

If the fix does not work for you come back here, and we can look deeper into your setup.
- Make sure pagefile is at least 2000mb, min=max, its a memory hungry beast until the official patch is released, could be filling the pagefile and crashing
- Load the offical Patch V1.09 if not already done so
