    Hi Jim this sounds like a nVidia video card problem. Fine out if you 
can what card you have.

    You need to edit the kernel line on your menu.lst in the directory 
/boot/grub/. Or you can do it with grub but this is tricky.

    Try this: Boot and wait until it quits loading. Then press Ctrl and 
Alt and then F1 and you should then see a prompt and sign in. Then do 
this: sudo lspci and see what video you have.
