Guild Wars 2

Hey, posted a thread before, I don’t know if it’s just sPvP, but I constantly black screen. Sometimes I play for an hour, sometimes I paly for 30 minutes, sometimes I don’t even as much as log back in. I never play for more than an hour without a blackscreen in sPvP. I tried to do PvE to see if it happened then to, but got bored after 10 minutes, sorry. After I black screen I alt+tab, right click and close GW2, and I get this crash error:

WHAT I’VE TRIED:
1) Reinstalling
2)Repair Tool
3)Underclocking GPU as low as possible
4)Lowest graphics settings
5)FPS limited to 60
6)FPS limited to 30
7)Crying like a little baby

None of these worked. In eed help! Game is completely unplayable right now.

Bump.
Help Us! D=

So far in this thread I’ve seen people complain about Thiefs, warriors, guardians, rangers, mesmers, necros, and elementals. The only solution? Buff engineers.

Bump I need hellllllp!

Every gaming session I get atleast 2 black screens. I tried the stickied solution, my setting was already correct. I’m using a Nvidia GTX 560 with the latest beta drivers. This black screen has been happening since ~BWE 2. It doesn’t happen with ANYTHING else, just GW2. They just happen randomly. Dungeons, PvP, WvW, PvE, I’ve had it happen during everything, my screen just goes entirely black and sound cuts out, all sound except weapon switching, I can spam my weapon switch button and hear the change, but that’s it. I can alt+tab out and everything, and restarting fixes it, but it’s SO frustrating to be destroying a sPvP match, and then black screen error with no rejoin mechanic. Any ideas?
EDIT: I’d also like to note that everytime I ALt+Tab out and right click->exit gw2, I get a gw2 crash error. Doesn’t just exit.
