I'd suspect a hardware error, perhaps the airport card. The SystemUIServer 
process controls all of the widgets in the top-right of your menu bar, so if 
one of them gets stuck (trying to get the status out of your broken hardware 
component), all of them gets stuck. This would also be why you can't shutdown / 
reboot.

Open your Applications/Utilities/Console.app and check for error logs around 
the time when you see this issue.

If you have any third party "extensions" / "haxies" I'd disable them for as 
long time as it takes to diagnose this issue.

Reinstalling the OS could fix something like this, or if not, time to take your 
machine to your local Apple Store / service center.
