blue screen in Fedora
 

Hellow all,
I have a fedora-version blue screen. Yes, the blue screen as of Windows.
Two days ago, I updated some utilities using Synaptic and tries to shut down the computer. However, it did not shutdown and got stuck with a blue screen with the rolling sand watch that used to give a way to text-mode. So, I just pushed the button to turn it off.

When I turned on the computer the next time, booting went well, doing starting utilities and so on until it stop right before the log-in screen. And it again was the blue screen with the watch where it stoped.

Simply I can't do or try to do anything...

It doesn't boot from CD-ROM; Booting disk didn't help either.

Is there any one who can help me with this?
I'm really frustrated and my wife is mad and demands Windows back.

ssh was blocked so that my friend couldn't help me. I'd like to know at least how to let ssh go through.

Any help will be greatly appreciated.
