Need help!

Installed my AMD HD 7979 Ghz edition.
The computer starts up, I get the windows and the small 5 dots circling. Then screen goes black and stays there.

Works just fine with integrated card of the mobo.

Running:
i7 3770k
Corsair HX850
Win 8

PLEASE HELP!!!
 
Ok. So magically it started working.
Now however I have the black line around my monitor, eventhough I installed all the drivers and everything. How do I get rid of it?

Another problem just came up. If I restart the computer it never boots back up. The only way to get back to WIN 8 is to go into BIOS and exit it without changes
