Guild Wars 2

Hi,
recently I’ve bought a new PC with an ADM Radeon HD 7900.
I have the common black screen issue described in the 3d below:

I’ve followed the instructions but anything….
I’ve tried different drivers from the official website but I can’t play at GW2.

Any idea pls?
Thanks in advance

Make sure ALL hardware drivers are up to date including BIOS. Also make sure to do a clean GPU driver installation by using something like Drivesweeper to remove any remnants of previous drivers before doing a fresh driver installation.
