Win8 can't be turned off, and turning off is equal to logging off.

Shutdown and logout are not the same thing. Logout means closing the account you use without closing it. If you have any questions, ask me.

If you shut down occasionally and crash, you can only press on/off key (if not, you have to pull out the power).

1) Is your computer not like this? If not, what did you do before turning it off or turning it off slowly? What hardware was installed and what was downloaded? Can you tell me? (If the machine crashes occasionally, please press the switch button to turn it off and then turn it on. )

Such problems are caused by software conflicts, inappropriate drivers and system problems. Can you restore the system or reinstall the operating system? Do not install software, patches, drivers, etc. , see if there is any problem with the shutdown? Don't install drivers, patches and software step by step, and don't install them if you find them inappropriate.

2) The other is caused by the card. For example, the temperature of hardware such as CPU is too high, or playing games, watching videos, running big programs, or using computers for a long time. At this time, it is very stuck. You should be patient and wait for the computer to recover slowly. Click on each page on the computer to recover slowly, and then turn it off after returning to normal. If it still doesn't work, press the on/off key (if the computer is turned on for too long, my experience is that

3) If the above methods can't be solved, first soft and then hard, reinstall the operating system, and don't install software, patches, drivers, etc. See if there is any problem with the shutdown. Don't install drivers, patches and software step by step, and don't install them if you find them inappropriate.

Please note: if you restore or reinstall the system, when installing drivers, patches, software and other things, you must not install things that affect your accident this time, otherwise it will be futile to restore or reinstall.

4) Hardware, such as hard disk and memory. , whether there is a problem, CPU and other hardware temperature is on the high side, if it is caused by hardware problems, it is recommended to repair.
