Windows 8 sleep mode problem?

So I've had my computer for about a month and I had the power settings to turn off monitor and computer to sleep after 5 minutes and it worked flawlessly. As of yesterday now though, after the 5 minutes is up the monitor will shut off but the computer wont initiate sleep. The computer stays awake, and only about %20 of the time it will actually sleep now. I can manually make it sleep by clicking on sleep but it won't auto sleep anymore rarely. I haven't changed anything on the computer at all, why is it doing this and how do I fix it so that it sleeps like it should under power options? Thanks.

    Hello beaverking

    It seems that some application has modified the settings or has some conflicts with the OS default configuration.

    It is a good idea to restore your computer to an earlier restore point and see if the issue is resolved.
