Game crashes when I try to go to Kalimdor or get close to a male troll!

I was using the Wod model client for a while ,but I kept crashing when close to a blood elf. The crash report screen kept saying "Wod models" so I removed the wod models. This sort of worked ,but it turned most NPCs into faceless black shapes as well as having a high chance to crash when near a blood elf. I downloaded the old wrath client and with it I can't get near a troll male without crashing. I went and downloaded bittorrent (I was using a different torrent) ,and tried to download old wrath again, same problems!


Also when I try to go to kalimdor I crash due to either troll male or "yellow scorpion"(that monster that roams durotar).


Anyone know what I should do?

Update: I removed and reinstalled a different version that I found on this forum. Now what causes me to crash are "doodads"
