No your English is perfect ^_^
Sry but i have the same problem, we need help guys....
This blackscreen is unbearable.
i have about the same system...
except my graphiccard is different.
So....hope you guys can help.
In my opinion the graficcards from Nvidea are much better than the cards from amd. I also had a amd Graficcard and I had exactly the same problem like you. 2 weeks later my Pc was bunch of shit. What I want tell you is please send back this bunch of shit and get a real graficcard from Nvidea )) How the guy before me tells you with 680 you dont make a mistake;) !!!
Unfortunately my Amd turns black again-.-
Straight a few seconds ago...
and now im online with my Laptop, so.... my pc is always still black.!
if this problem never end, i will send this graphiccard back and i will buy a nvidia like my mates said.
I hope you found help friend
