Apart from the random crashes, freeze-ups and repeated rebooting problems, another frequently encountered problem with Windows 7 is that of system shut down. Most often the system devices continue to work even after a shut down has been initiated, requiring the user to physically switch off power supply to the PC.
In a few machine makes such as those from Asus, irrespective of the mother board versions, the problem seems to be simulatable, while in yet a few other machines the problem occurs randomly. If you are keen on exploring the problem on your own, you could start by checking what all processes and devices are still active post the shut down command. Usually, power management settings associated with the devices, antivirus settings etc influence system behavior on shut down, or while the system gets into the hibernate or sleep modes.
Asus users, however, have a tried and tested solution to this problem, directly attributed to power management settings of the IEEE 1394 Bus Host Controller. Get to the specified host controller group in the Device Manager and look up the properties of the host controller device within the group, the “VIA 1394 OHCI Compilant Host Controller”. Change the settings to allow this device to be turned off to save power and the system shut down process will no longer be a problem.
While trying to look for the power management settings specific to a device, some users have also reported that the corresponding tab is missing from the device properties UI. In that case, first check if you have installed the latest device drivers. For external devices such as USBs, remove the device, disconnect, reboot and plug in the device to install the device again with power management settings.
In the absence of a power management tab, you could also directly disable the device from the bios settings; only remember to make the changes consistently either from the UI or bios settings.
If you are facing a problem with system shut down only recently, check if the Windows automatic updates option is turned on, and if any latest updates have been installed on the system. An update icon on the ‘shut down’ button should indicate the details, if any. It has been found that the problem is the KB976098 update related to Time Zone settings released during November this year. Uninstalling the update seems to rectify the issue.
Do back up system contents and settings before going ahead with any major changes. Creating a restore point may be an easier way to get back on track if the changes aren’t successful.
