It started a few days ago while playing ingame in both pve (roaming, dungeons, fractals) and pvp where i experienced screen blackouts at random times. when this happens i can still bring up the options menu and even the character select\log out menu but they don’t work when clicked.
I can still hear faint ambient sound from the ingame background noise but nothing more.
Like i said this blackout happens randomly, sometimes after an hour and sometimes after 5 minutes. I can easily Alt+Tab to my desktop and use all other programs and web use as normal, the internet works fine as do all of my other comp functions. i’ve been using the same comp for this game since launch and this has never happend to me. I use the 64bit client on windows 7 ultimate. Any help on this issue would be greatly appreciated.
