Screensaver won't come on

I have an odd problem: My screensaver will not come on.

I am running Windows 7 64 bit, and my videocard is a Radeon HD 5770 with the latest drivers.

My screensaver is set to come on after one minute, but it never comes on. I can preview it fine, it is Window's default ribbons screensaver.

My power settings is set to turn off the display after 10 minutes but that doesn't work either.

I have my PC hooked up to two screens, an HP LCD and a Samsung HDTV.

Please help and thanks.

  1. Do you use a wireless mouse that you can switch off or an usb that ou can unplug? Sometimes only small vibrations on the desk create i/o's from the mouse and reset the 1 minute counter.

    You may have something running in the background of your PC that is preventing it from starting because the screensaver is based off of idle time.

    I would recommend using Autoruns, which can be found HERE, and see if the issue corrects after taking out some of the things booting up when Windows does.
  3. I found out what the problem was. My videocard's 2D speeds were clocked too low.

    I have a Radeon 5770 and the 2D speed was 157 MHZ. I used GPU Tweak to increase the 2D speed to 450 MHZ and that did the trick!
