Here’s the commonly reported problem scenario people encountered: On attempting shutdown, nothing at all appears to happen for a prolonged period of time.
Eventually, an “End Task” window appears, wanting to terminate DEVLDR32. No matter what one does, one ultimately is locked out of shutting down other than by a power switch shutoff.
When Windows XP won’t powerdown automatically, the APM/NT Legacy Power Node may not be enabled.
MS-MVP Jim Pickering advises the following as one approach to these problems: Restart the computer.
This may be a global symptom emerging from several distinct causes, because, by default, XP executes an automatic restart in the event of a system failure.
Therefore, more or less anything compromising the operating system during the shutdown process could force this reboot.
My best advice is: Check all drivers for all hardware devices to ensure that they are the current best for Windows XP.
Most Win XP shutdown problems reported thus far have been that it reboots when shutdown is attempted.
Press F8 during the restart and select “ Last Known Good Configuration.” If you catch the problem when it first occurs (meaning you likely have installed only one or two drivers or new service), this will return you to a previous working condition.
