Recently, I have found that, much more often than not, following the normal procedure for shutting down my PC, Windows XP simply hangs on the blue "Windows shutting down..." screen and will not close.

I turn off the computer manually, and, next morning, there is no after-effect of any kind. But, I don't like the fact that Windows won't shut down properly by itself and wonder if this is indicative of any more serious problem.

Is there a way to fix it? (Please don't say, "Yes, don't use Windows XP"! :-))

Thanks.

Don
