This has been a problem for me since Vista. I was hoping that once I upgrade to Windows 7, this problem would go away, but it didn't.
I set my screensaver to the slideshow that comes with Windows. The folders I use is on my only SATA HDD. The power scheme is the default setting.
Most of the time, the screensaver slideshow would not come on. Instead, the desktop would be displayed until the power scheme turns the monitor off. I set the screensaver to come on after 15 minutes, and the LCD monitor to turn off after an hour of inactivity.
Again, I had this problem already with Vista, but it's the same issue with Windows 7. Does anyone have any idea why the screensaver doesn't start after 15 minutes?
Thanks in advance.
