Guild Wars 2

I can play for about 10 minutes and I get a black screen. Sometimes if i wait 2 or 3 minutes the game will come back but most times all i get is a cursor on the black screen. I have to restart my computer. Any one have any ideas how to fix it?

I have already turned off my firewall and lowered my in game settings.

Last time I had black screen issues with the game, I had to reinstall the video drivers. :/

Okay. I will try that. Thanks
