Win10: Screensaver won't turn on, display won't turn off

[Skeefers]

I just upgraded to Windows 10 from Win 7, and am having the following problem:

After sitting idle for several hours, the screensaver never activates and the display doesn't go into power save mode. I've tried numerous settings to resolve it, but with no luck so far. Currently the settings I'm using are the same as they were in Windows 7, where everything functioned correctly. These settings are:

Power options: High performance (modified)
HDD set not to turn off
USB selective suspend disabled
PCI Express link state power management disabled
Minimum CPU state 100%

Screensaver to activate after 15 minutes
Display to shut off after 30 minutes

These may not be the optimal settings, but they worked in Windows 7, and even using more restrictive power settings hasn't resolved the issue since the upgrade. Any help is greatly appreciated.

Try setting the display shutoff timer to the lowest possible setting, then unplug all of your peripherals afterwards.
