Desktop not loading

I believe this is the computer I have, but there may be minor differences:

A bad image caused Trisquel not to boot. I have created two additional disks which allow the boot, but either Full 64 or Mini 32 doesn't show on the screen after the boot. Up until then everything is fine, but the desktop never shows up, it is just black.

I know this could be many problems but am hoping that someone can spot the problem based off of my specs.
