Hello, so I've gotten an MSI HD6850 Cyclone and when i power up the computer I see BIOS normally i can get into it no problem, I even see the windows logo and booting dots but after a black screen during boot i see only black screen.. but it has signal cuz the monitor is not showing no signal, only it's blank, from first when i wanted to install drivers I saw the windows normally, but when I installed from then I dont see. Any solutions please?
