[ubuntu] Blank screen during installation

Hello.
I wanted to install Ubuntu 13.04 x64. I've burned cd, booted it. Then screen with options appears. I chhose "Install Ubuntu" (when I try other options the same things happen). Now I see only blank screen - nothing happens.
I tried also with usb installation (pendrivelinux) and other version (12.04) - the same problem.
My notebook is Asus k55vj with preinstalled win8.

Thanks in advance!
