Desktop PC won't turn off the display automatically?

I set the power plan to both Balanced and High Performance and set the time to turn off display to 1 minute. However, no matter how long I wait, the display just won't turn off,let alone entering sleep mode. I have left all the Homegroup and even prevented every devices from waking up the PC (such as mouse, keyboard). The apps I have installed and run in the background are: Kaspersky, NVIDIA Geforce Experience Ceter, Tuneup Utility, Realtek HD Audio Manager, Rainmeter, Dropbox. Please help me figure out where the problem lies. I don't form a habit of turning off PC when I leave and I don't want my display to burn out. Thanks!

I have the same issue. – AlbertoPL – 2014-10-19T17:50:09.793

forgot to mention, the OS is Windows 8.1. I've installed all the updates. – Catiger3331 – 2014-05-28T01:01:07.783

In very rare cases, it will turn off the display normally, however I did nothing for this to happen. And the problem arises again when next boot-up. – Catiger3331 – 2014-05-28T01:08:21.550

I'm wondering if the problem is with OneDrive, I never use it and don't know how to turn it off. – Catiger3331 – 2014-05-28T01:09:39.050

Did you change the power plan settings form TuneUp Utilities? – Harshil Sharma – 2014-05-28T01:56:16.453

I have this exact same issue and have fixed it.

For me the problem was due to my Microsoft Keyboard (http://www.microsoft.com/hardware/en-us/p/sculpt-ergonomic-desktop#support). The solution is to simply install the keyboard and mouse drivers from Microsoft.

I have my power plan set to performance and screen

If you leave Windows Media Player open, it can prevent the screen saver from activating (handy if you're watching a movie with it). You can go into its settings and enable "Allow screen saver during playback."
