Mac Pro 2009 will not restart or shutdown

[DougieBaby99]

hello, my mac pro 8 core intermittently will not shut down or turn off. Happens about 20% time. When I tell it to shut down, the finder will quit, finder menu goes away, the dock will stay on the screen and the computer will not turn off. This happened right after I used bootcamp to install win 7 on a dedicated HHD. I was hoping upgrading to 10.6.3 will fix, but the problem still happens about 20% of times. I'm willing to re-format and re-install snow leopard if thats what it takes, but I'm hoping someone smart here can help me. Thanks

I everyone.

I have the same computer as you, and the exactly same problem.
I would like to solve this issue cause is really anoying.

I've already asked for a solution in this forum, and it was sugested to me, to reset de SMC (sistem Management controller).

But thats the last thing to do, if any other works. And I haven't done it yet.

If you have any other idea plese share

You both really do need to perform the SMC reset. It really is the most likely solution given the information you've posted.
