I am also having that same problem with Mint 12 Gnome, the tool bars are missing and there isn't any main menu, installation completed without any problems. The only things on the desktop are the Home and Computer icons.
I was previously running Mint 11 Gnome without any problems, and I can get Mint 12 LXDE to work, although I can't say if it is working 100% correctly having never used it before.
My computer is one I built several years ago, it has an AMD 64 2800+ processor with a Via K8T800 chipset, and 512 MB of ram. The Video card is a nvidea GeForce 5500.

Someday, maybe I'll figure out exactly what the hell I'm doing.
