Guild Wars 2

just as the title says ,I seem to keep getting black screens when ever I try and do some story mode quests,i can play for hours non stop doing pvp exploring,doing the area quests and crafting with no trouble and when I first started playing this game (been about 5 or 6 weeks now) everything was fine no black screens what so ever but the last 3 or 4 weeks its been black screen after black screen and its getting frustrating having to do every story mode chapter over and over again hopeing I wont get the black screen. I have tried this https://forum-en.gw2archive.eu/forum/support/tech/Black-Screen-Issue-Nvidia but still happens any other ideas to try? or maybe you guys can think of putting in a check point system for story mode? i have no issues with any other games i play from the new splintercell to neverwinter all work fine so im at a loss on what to try here to fix this

wow so this is happening to me this morning.,after I get a black screen and have to restart the game. now I cant seem to log on and by the looks of it from reading some of the posts on the forums this has been happening for over a year now and they still cant be bothered to fix the issue,glad ive only been playing this game a few weeks and haven’t sunk to much time in it.
