I suspect that my problem is associated with power management. My power management program allows my PC, after a period of unuse, to first go to a screensaver (Sea Scene) and then certain components shut down including the monitor which turns into black screen. I've had no problems with this set up. As soon as my move my mouse, the screen saver appears and when I click its "exit" icon, my PC goes immediatly to the full desk top.

Recently however during the past several days, when I move my mouse after having the PC unused, and after clicking on the screen saver "exit",  it takes the monitor a long time to show the full desk top. It wakes up slow, the icons appearing one at a time, often without the "Start" bar (lower left). Further, when I click on any of the icons, nothing happens right away. Instead, the screen turns white momentarily, then turns black and eventually, the screens turns normal. If I reboot while this phenomenon is occuring, I get a normal desktop.  I hope the explanation is clear. Any help is appreciated.

Hibernation can be thought of as shutting down, with the exception of how things start up.  In a normal reboot, shut down etc, you get your clean desktop.  In hibernation, when you awke your PC, your desktop should return just as you left it.  This always sounded dubious at best to me, and I doubt it works as well as it would have you imagine.  I've never truly tried it.  It seems as though it would be more useful for laptops.

Since I was able to resolve my original (slow wake up) problem, I will leave my power management set up as is and not mess with hibernation. But thanks for the various inputs.
