If you still have trouble run battlefield cleaner to flush out your video cache files

Still no joy?

Trash your BF2 cache files
Path:
C:\Users\'your user name here'\Documents\Battlefield 2\mods\bf2\cache

Throw EVERYTHING inside the folder named cache away.
don't worry the files will be replaced with new ones when the game restarts.

Still CTD?

Make a new user and try to join a server.
Don't worry about your settings yet, battlefield cleaner can transfer old
settings to the new one later

OK
Some other things you can try before you uninstall/reinstall.
Backup your BF2 folder that's inside your documents folder. Once you have a backup delete the original from your documents folder.
Try starting PR from your PR shortcut
a new default folder is created
link to your online account.
If all goes well (CTD gone) all you have to do to get your custom settings back is copy your 'control' file from your backup to the new profile folder.
path:
C:\Users\your user name here\Documents\Battlefield 2\Profiles\0002
note: you may not have a 0002 folder so use 0001

You can also set game controls to default then quit and reboot. That worked for me after tweaking settings left me with a lag issue I couldn't fix by setting everything back to the way it was.
Good luck
