Installation of 8.04 Freezes

[teejay17]

Hi, when I try to install Ubuntu 8.04, the machine freezes about a quarter of the way into the progress. It will stay like that for hours; I have to do a hard shut down.
How can I get beyond this freeze? I know it's a hardware/software issue having to do with my Audibly 2 sound card (I can't install the driver in Vista either, or else my system goes berserk).
Anyone know how I can get Ubuntu on my machine? Or at least boot into LiveCD?

Memory? Graphics?

Freezes occur for one or more of three reasons: You don't have enough RAM The CD is corrupted (the .iso was corrupted during download or during the burn) You have faulty hardware

It will be number three—I have a Gig of RAM on this PC, and the CD is fine.
What I'd like to know is how to install Ubuntu without having to take out the corrupted sound card. Is there a way that I can do this? A work around of some sort?
I thought that by disabling it in the BIOS, and going back to onboard sound, would have been sufficient. However, that hasn't worked as of yet.
