Hello, I have recently been having a problem about my computer entering it's stand-by mode. I have no problems during start-up or shut down. I can restart the system and shut down the system with no problems at all. When I click Start, Turn off Computer, and stand-by, everything appears normal, the desktop icons, and bar disappear, and it enters the blue screen, with the windows logo and the Windows is preparing to shut down caption under it, or a similar caption. When it gets to that point, it hangs on that blue screen with the logo like its trying to shut down but can't quit complete the process. I have to hold down the power button to shut it down, therefor not entering stand-by mode. Is there a simple fix to this, and help is appreciated thanks.
