I wanted to try out ubuntu on my desktop PC. I downloaded Ubuntu 12.04 64 bit version and burned it on a CD. When boot the CD and got those option to chose if I want to install ubuntu or run it from the CD. I chose to install ubuntu. When I press enter it's going to load and you'll see a "-" sign in the top left corner of my screen. After that nothing happends.
edit I may not answer my own questions so i'll edit this one but i tried to run the installation with acpi=off and now the installation starts. If its still needed my graphic card is GTX550 ti and my processor is Q8400 @ 2.66 ghz
