Gnome 3 in Debian not working

Earlier today I installed some software updates through Debian's Software Updater Application. Everything went fine and it said I should reboot the machine for some updates to take effect. When Debian booted though and I logged in with gnome3 (which works since I previously installed drivers for my graphics card) it would show my desktop icons but he gnome interface wouldn't show up. I rebooted and selected gnome classic and it worked, so im just wondering if it was an update error and if there is any way to fix it. Thanks All

Moved to other OS / Distro support.

Which Debian? (stable, testing, unstable)
