Vista not shutting down my PC!! Help!!!

[Guest]

I just installed Vista on my new PC (680i EVGA Motherboard) worked great,
still does, but after I did the vista online updates and rebooted it won't
shut off my pc!!? Vista itself shuts down ok, my keyboard also, but my
motherobaard, power supply, and all fans stay on, I let it go for about 10
mins. and still won't shut down, I have to manually hold down my power button
for it to turn off, someone help!!!!!

Someone else posted here with the same problem. He said that if he just
left the machine alone overnight that it eventually shut itself off.
That doesn't help you any, but I'm curious to know if yours behaves the
same way. Same bug?
