Guild Wars 2

Hello everyone, i noticed lately when i enter WvW and its usually when we are going to take over the stronghold, gw just crashes, so i restart, relog, run back there for the xp and when i get there, crashes againg, the next time i relog, the stronghold is already taken…
Its really frustrating as its happens to me a lot recently and it just sux to be left with nothing when you attack something for hours…
As i got annoyed at that i thought, must be something with drivers maybe, so i updated the drivers to the newest one(nvidia – beta drivers 3.10, before i had 3.07). That proved to be even worse, now Wvw crashes cca 20 seconds i enter.

Can someone make a suggestion what to do or either one of you have similar problem and know how to fix it? Or maybe link to the post where this is already discussed (i searched the first 10 pages and the problem is not among them).

ty and hope this gets fixed asap
