When AT HOME, my computer with Windows 7 will not shut down properly. It will go through the stages then hangup on the "shutting down" screen for 5 to 7 minutes. Then I get a Blue Screen and then it reboots. Works fine for everything else. Only does this at home. When I am anywhere else it works fine. At home I have Qwest DSL with a Motorlola 3347 wireless router.
