Game crashes near Dalaran

Everytime I get near Dalaran in Crystalsong Forest (or even in Icecrown), my client crashes. I get these 2 error messages:

I'm running the game on a brand new pc, with GTX 970 and 8gb ram so it should be no problem at all. I tried disabling my addons, and also deleting my WTF and cache folders, both of which did not help.

Please help ):

it is because of WoD models.
