As other have suggested, check the processes.
I had a very odd problem recently with 7068, and the issue was so simple and silly. Having an SD card in my computer's SD card would not allow it to shut down appropriately, although in my case it usually hung at the "Logging Off" part of the process. Soo.. if you have an SD card in your computers slot, try removing that. I would work to isolate which process is causing the problem. Does your screen quickly flash dark, as if the window saying "waiting for programs to close" were to come up, when you shut down your computer, before showing the logon screen background? That seems to happen to many folk with shutdown problems.
Try booting in safemode and see if you have the same issue. Perhaps you may wanna try going to msconfig and setting it to diagnositcs startup since that will remove unneccesary processes and help you isolate the problem.
Good Luck!
