I have had Guild Wars 2 since it came out, and no problems.
Not played for a week and now when I play, I get Black Screen at random times.
I have not changed any Hardware on my PC or Drivers.
It only Started happening two nights ago.
I have already tried the solution posted on : https://forum-en.guildwars2.com/forum/support/tech/Black-Screen-Issue-AMD-ATI/first#post38195
This has not solved my problem.
My System Specs are the following
Operating System: Windows 8 Pro 64-bit (6.2, Build 9200) (9200.win8_gdr.121119-1606)
