black screen. I will plug the PC to the internet and redownload drivers (I have it offline to test some other apps behaviours without internet connection). I'll let you know.
thanks for the help.
UPDATE: ok, it was the drivers, a friend tried to impress me with the latest beta drivers, and I just reverted everything back to the stable drivers and magic happened.
thankfully that was one of the reasons of getting it offline... hehehe. now I'm at full speed, let hope we don't find another bump on the road.
thanks everyone for their help.
