Freezing On Shutdown And When Going To Sleep?

Nearly every time I shut down my computer it goes fine until reaching the ring that says shutting down then the ring freezes and nothing happens. I have to hard boot it every time. When i put it to sleep or hibernation similar thing happens: screen goes black, the hard drive is working, and then nothing changes, everything is still on hard drives and all. I leave it alone for awhile to see if that helps but nothing happens while i leave it. It happens 90% of the time. Computer specs are uploaded with the profile, on that computer icon.
