Laptop operating system help?

Alright so I have an older windows xp laptop (Toshiba Satellite A105-S4064) which i don't use anymore. I have tried to install Ubuntu 11.04 on it from a flash drive and it got stuck with the Ubuntu logo booting screen. So I turned it off and re-booted from the usb and same thing happened. I thought maybe the usb was corrupt so i re-installed Ubuntu on the usb and tried again. It still didn't work. And now when i turn on my computer the screen doesn't even come on it just turns on and doesn't even show a boot sequence. I'm pretty positive that its not a issue with the screen. I even tried the recovery disk that came with the pc and nothing. Im not sure what to do. I still want to install Ubuntu. But nothing is working. Its as if windows xp was deleted in the Ubuntu install process but Ubuntu never installed to replace it. Any tips?
