I have downloaded latest PTR patch today and found out that it crashes during or after the load. First time I selected character, it loaded, rendered few frames and then crashed without any error message. Next time it crashed immediately after the load. When I delete config.wtf file, it does the same: first time it shows some frames and crashes, then it crashes right after the load. Strange thing is that it does not show any error message.

My system config is: Windows Vista 64bit (Ultimate), Athlon dual core processor, 2 gigs of ram, Geforce 8800 (gts 640mb).

I didn't log on test realm for a week or so, but it worked before :).

Anyone had encountered this problem?

edit: I tested a different character, in different location on a different account. Still crashes.

Q u o t e:

Crash to Desktop

Some users of Vista 64-bit Editions are experiencing a Crash to Desktop. These crashes just happen and boots you back to the desktop without any error messages. Data Execution Prevention (DEP) seems to be causing some of this. You can try turning it off for a program or turning it off completely to see if it is causing your mystery crash.

* Turning it off for World of Warcraft:
Start -> Control Panel -> System and Maintenance -> System -> Advanced System Settings -> Performance Settings button - Data Execution Prevention tab
Select Turn on DEP for all programs and services except those I select:
Click Add...
Browse to WoW.exe and double-click it.
Hit the Apply button.

* Turning off DEP/NX: http://vista.beyondthemanual.com/2006/11/vista_tip_turn_off_data_execut.html
