I have done every recommendation posted to correct this and it hasn't worked. I've checked settings, unplugged devices, turned off scanners, turned off printers, disconnected external hard drives. This has been going on for months and driving me crazy.
Until.... the other morning and my screen saver was on. I finally figured out why. IF leave my computer with all programs closed, it won't work. IF I leave any program open, (weather, word, chrome... ) the Screensaver kicks in as designed. But with my desktop running, it doesn't work. No matter if the picture is set to change once a day or every 5 minutes. All programs closed, nothing. Any program open, perfect.
WHY?
