Improper shutdowns..... How to fix?
My Windows computer frequently experiences abnormal shutdowns, the system fails to close properly, and sometimes it shuts down automatically suddenly. I have checked the basic settings and restarted the computer, but the problem persists. I would like to know how to troubleshoot possible causes, including power settings, hardware failures, driver conflicts, system file corruption, or other conditions that might prevent Windows from completing the shutdown.

First separate a shutdown that hangs from an abrupt power loss or restart, because they require different diagnostics. Note the exact time of the next incident and inspect Event Viewer > Windows Logs > System for Kernel-Power event 41, unexpected-shutdown event 6008, bug-check data, WHEA hardware errors, disk errors, and the events immediately beforehand. Event 41 only confirms that Windows did not shut down cleanly; it does not identify the cause. If BugcheckCode is nonzero, preserve the memory dump and investigate that stop code. If it is zero and no dump exists, check power delivery, battery or power supply, temperatures, memory, and firmware. Return any overclocking to defaults and install current BIOS, chipset, storage, and graphics drivers from the device manufacturer. For a shutdown that merely stalls, perform a clean boot and run DISM followed by SFC. Change one item at a time and track whether the failure returns.
