Hey guys, I have an issue with my computer and Window 7 that I was hoping you could provide insight on how to fix. Recently I have noticed that Windows 7 doesn't want to shut down. Heck, it doesn't even restart and Hibernate. When I go to Shut down the only option it provides is Log Off. You can shut down after the the computer Logs Off my account, but this wasn't the case before. I also feel it might be important to note that the computer prevents me from entering the Task Manager and Ctrl- Alt- Del no longer does anything. Is this an issue with the OS or could this be something like a Virus. Any help would be appreciated. This issue is driving me nuts. Thanks for the help guys, and sorry for any inconveniances.
