This post has been updated from information that is available with Roma Surrectum II but the same issues apply to IJ and hence possible solutions.
The game crashes after a battle.
And the more troublesome are the random CTD that sometimes appears after an especially long and soldier-filled battle, straight after clicking on the continue button. For those of you that are having "RAM related" CTDs that have 3 or 4 GB of RAM, you're correct, it's not your hardware, but, if you are running a 32 bit version of XP or earlier, there is a problem where applications can't address more than 2GB of RAM. This is what usually causes those crashes after a huge battle.
It would seem that this is a hardware issue, since it only appears in resource straining situations, but our tests can't find anything wrong like overheating. If this happens to you several times, please report it with the maximal informations possible in-game and outside (heat of hardware, usage of memory, CPU, GPU; the more, the merrier). It seems that waiting around 30 seconds before clicking on continue reduce this somewhat. This lets some of the RAM "clear out" so the campaign map can load. Another workaround solution is this: if your computer comes with an activity light, make sure that the light is no longer blinking rapidly before proceeding with what you are about to do after a battle. The rapid blinking light is simply telling you that Rome Total War is still calculating the aftermath of the battle, including troop loss, movement points, characters affected, population change, etc.
Here are additional things that can be done to help deal with crashes after battles:
This is to help improve performance and reduce CTDs.

The game crashes while loading my savegame.
Your savegame is corrupted for some unknown reason. The good thing is that it happens rarely, but that is not really a consolation for you right now. There is no way around this, except loading an earlier savegame or starting a new campaign. Another good thing is that you have those older savegames to revert to. Right? Right. Anything else would be foolish, of course, sorry for doubting you.
I saved my game right before a battle begins, and the game crashes after the battle.
Yes, that's true. You need to always save on your turn, and never right before a battle, as that provokes CTDs. Reload an earlier savegame and you should be fine. Don't have an earlier savegame? Foolish. Make sure you retain them in your next campaign.
I have just taken an enemy settlement, and the game crashes when I select its fate.
Are you sure you didn't save the game right before the battle where you won the city? If you did, see the above point. Otherwise, you may have some success using Lusted's trick with corrected_regions.tga. It may be quicker to just revert to an older savegame though, if it's not from very long ago.
I've just played through a huge battle and it crashes as soon as I click to close the battle summary scroll to return to the campaign map.
- Make a backup of RTW/IJ/data/world/maps/base/campaign/map_regions.tga.
- Copy corrected_regions.tga from your RTW directory into the folder where you found map_regions.tga. Then rename the file to map_regions.tga (you may have to delete map_regions.tga first).
- Start IJ but do not load your savegame. Delete RTW/IJ/data/world/maps/base/map.rwm.
- Load your campaign. Play the battle and see if you get past the crash. If not, revert to an older save.
There is no certain way to fix this, but there are currently four ways that I know of that are reported to minimize or eliminate them.
The game crashes during battle.
- Leave the battle summary open for 10-15 seconds instead of closing it right away.
- Do not use the Miles Sound System, but rather DirectSound3D. You choose this by going to the OPTIONS in the game menu, then choose AUDIO OPTIONS and select another SOUND PROVIDER.
- Replace RTW/IJ/data/world/.../map_regions.tga with RTW/corrected_regions.tga. Delete map.rwm and do not use the trivial script to start EB the next time around. After quitting IJ again, copy the newly generated map.rwm file into sp game backup.
- Try the suggestion of Theages in this thread.
This is unlikely to be a problem with IJ, but rather something with your hardware. Yes, RTW vanilla works fine, but we're taxing your system more.
Unit and Building Cards Appear White
- Download and run Memtest to ensure that your memory is doing alright. If not, you could have to change your memory speed in the BIOS, or replace one or more of your chips.
- Try to upgrade your video drivers.
- Try to DOWNgrade your video drivers. Some are more stable than others. There is a suggestion for a driver version for ATI cards in the validation thread, which is the one I was using at the time with no problems.
- Run Scandisk on your hard drive. You find this by right-clicking the drive in question, then choose Properties and click the Tools tab. Finally click the "Check now" button on "Error checking".
Some unit cards and building cards may sometime appear white. While annoying, there currently exists no solution to this problem. It would seem that once more, there is just too much of them, and the aging engine can't cope with it.
Many, many thanks to merlinuscdxx and Roma Surrectum II for this.
