GNOME desktop fails to start, only KDE and Xfce

[MarcoA]

In consequence to a problem, GNOME desktop never come up again, so I upgraded from FEDORA 9 to 10, hoping to resolve this issue, but It didn't.
What can I do to make it COME UP again?
Maybe something is wrong, but I don't know hat to do.

Best Regards

Don't you remember what you goofed on? Gnome usually not broken in Fedora 9, usually KDE in the begining.

Start your terminal:

su -
yum groupinstall "GNOME Desktop Environment"

What does it show at this moment?
