One, why the computer can not shut the machine
1, the most common is the computer in the Trojan or virus, under the influence of Trojans or viruses, resulting in some computer drivers can not be normal operation, or even if not in time to clear the computer can not be shut down.
2, computer hardware problems, but relatively few, such as the computer's power management module and other reasons that the computer can not shut down normally.
3, the third situation is more, because the background to run the program is more, not in time to shut down, then the computer before shutting down these programs, and thus wait for a period of time to shut down, but this does not belong to the scope of the machine can not be closed.
Computer knowledge
Second, the computer can not turn off the machine how to do
1, first use anti-virus software, such as the overall scan of the computer to see whether it is due to Trojan or virus caused, if it is, to delete the impact of the program or file.
2, for the hardware problems caused by the shutdown then relatively difficult to exclude, if the conditions of friends suggest a change of the motherboard to try, or the power part of the focus of inspection. But the odds of a problem with hardware are slim, and you don't have to worry about it.
3, everyone in the shutdown time is clicked on the lower left corner of the shutdown, this shutdown if you do not close your own running some of the programs, will cause the computer shutdown before the running of the program to clean up, if the running of the program too much, will cause the computer can not shut down, this solution is in the shutdown, We shut down some of the programs that we run ourselves.
