Guild Wars 2

Shameless new tread instead of bumping my old. Im desperate.

I have done :
- Delete local.dat
- Done the -repair
- Updated my drivers
- Complete reinstall

Now game “crashes” ,sends me back to windows screen.
The game is still running in the background, i can execute skills and even mouse
pointer looks the same as in game plus some icons pop up if move the pointer(like the + for zoom on worldmap.

New crashlog:

Hi and thanks for all the help, sadly im still not able to play gw2.

Done the -repair option
I have deleted the local.dat
I have updated to drivers to NVIDIA 331.65
Overwolf is gone
Done a complete reinstall of the game

Screen goes black after 1-2 min now and after 2-3 min im back to windows.
I still hear the sound and i can use skills in game (i hear me doing them).
After a couple of min the game crashes completly.

This is my new crashlog:

GW2 worked just fine until 2 days ago.
Now i crash after 2-4 min in game, sometimes the screen goes black and
sometime it goes back to windows screen and i can hear the game in the background
the computer is locked up.

Im far from a computer wiz but would be greatful if anyone could help me.
