This worked for me, apparently all the ingame menus are silverlight based. Added bonus: the menus seem snappier.

I was crashing every 5 minutes in uldah, every 10-20 minutes in other places. Now im not crashing at all, i even turned general draw quality up to 9 (dof+ao off, will test later with them on) and game not crashing. I just sat in the middle of a bunch of ppl in uldah and crafted stuff for 15 minutes and my card didnt even hit 60% usage, clocks seems much steadier. Im pretty sure silverlight and the game engine fight for control of the graphics device and eventually silverlight takes over and makes the game crash.

This would also explain why Nvidia cannot reproduce the issue. Either they are using older silverlight, have hw accel off, or dont have silverlight installed at all.
I uninstalled it and I crashed 5 minutes in. Not it.
