It looks like that you need to set v-synch on in your catalist center, because i turned it off for older game, which doesnt have v-synch setting and when i tried to play guild wars 2 it froze again.
I turned it on again and no freezing.
I bought this game on 5.2.2013 – I have experienced random freezing (hard restart needed) from the start in 20 minutes intervals.
Googled the issue and found something.
I think that all of you as me have asus motherboards. So I updated the bios and turned off all of the bios overclock settings, which were set on auto by default.
This helped, played whole day without freeze.
