Hello and welcome,
Have you tried booting in text mode, or with one of the optional VGA modes?
Do you see scrolling text during boot, then a black screen at the end? Ubuntu does that on one of my machines until I tap the enter key. Then the desktop appears.

Also, what Ubuntu version or Live CD distrobution are you using? The reason I ask is because it should be relatively new. For example, there should be no issue with anything released from Oct/Nov last year to date. Try Fedora 16 or Ubuntu 11.10 or Linux Mint 12. Any of those should work.
