Almost all PC users with Windows 7 installed, faced with a problem when the computer does not turn on, try to fix it in every way. In the case where the PC does not turn off or freezes when disconnected, most of them simply unplug the power cord or remove the battery from the laptop, which can lead to data loss or damage to the computer's hardware.
Instructions
Step 1
First you need to decide where the malfunction lies - in the hardware or software of the computer. In the first case, to identify the malfunction of the components in the computer, you must boot from under another OS. For this, a LiveCD or an operating system installed in another disk partition is quite suitable. If the problem persists, then the problem lies in the hardware of the computer. Verification of components is possible only by replacing them with ones that are known to be in good working order.
Step 2
Software
If no malfunctions are found in the hardware of the computer, you can proceed to the software test, although in most cases the test should be started with it. Delaying the shutdown process can occur if the drivers are malfunctioning. In this case, reinstalling them can help.
Step 3
USB hub
Oftentimes, shutdown hangs are caused by incorrect installation of Windows. This malfunction is especially common in laptops, the cause of which lies in the IEEE 1394 bus controller. To eliminate it, just check the box in the hub settings.
Step 4
Also freezing on shutdown can occur when the computer is infected with malware. To check, you need to download the latest anti-virus databases and scan your computer. It is advisable to check it with at least two anti-virus utilities. Dr. WebCureIt or AVZ 4 will perfectly cope with this task.
Step 5
If, after completing all the above steps, the shutdown process remains invariably long, then the problem must be looked for in recently installed applications or system services. Most likely, one of them is causing a conflict in the system. The conflicting application or service can be viewed in the event log. Typically, disabling a service or uninstalling an application (unless specifically required) will fix the problem. Also, the number of startup programs affects the shutdown time of Windows.
Step 6
Shutdown hangs can also occur when BIOS settings fail. If the message "Now the computer's power can be turned off" appears, in the BIOS, in the power management section, you must enable ACPI. Also, in some cases, a factory reset can help.
