How to do the computer automatically shuts down after a while?
Hello, the computer will automatically shut down and restart automatically. There are reasons for this. Please check the following 5 items, focus on 1 and 2 !1. Hardware overheating: Disassemble the CPU,
graphic card
fan cleaning, add heat sink thermal grease, increase the forced cooling fan; 2.power
output: hostpower
The output power is insufficient or unstable, check whether the power matches or replace the power supply; 3. Hardware connection: graphic card
in the chassis, memory and other hardware plugging contact is bad, check whether the connectors are loose; 4 Improper setting: Control Panel - System - Advanced - Startup and Recovery - Settings - Automatic Restart - Uncheck; 5. Computer Virus: Upgrade Virus Library Full Disk Antivirus, or 360 Guards → System Tools
→ System First aid kit → repair. In addition, poor contact or damage to the memory module will also cause automatic shutdown and restart, blue screen of death, it is recommended to disconnect the power strip after the power is turned off and wipe the gold finger and then reassemble. If there are two memory modules installed on the motherboard
, check whether the frequency is consistent, and then unplug the computer (only one memory stick is left) to determine if one of them has a problem. Satisfied please adopt!
It may be poisoned, it may be stuck, so it will shut down automatically
Automatic shutdown reason:
1. The host has poor heat dissipation, power failure, and motherboard failure, which may cause the computer to automatically shut down or restart automatically. (Reboot is an important feature: sometimes shut down, sometimes restart)
2. Virus Trojan destruction, when the system core components are damaged, the running computer may automatically shut down. Jinshan security experts are here to provide you with special killing tools and system repair tools, please click on the quick download.
3. Among the running software, there are some software with the option to complete the shutdown of the task, the user may not pay attention, turn these switches on.
These softwares are more common, such as Xunlei
, express, antivirus software
, BT download, video playback and so on. In the software settings, there are actions to automatically shut down after completing a task. But the general default setting is off. The goal is to automatically shut down the computer after completing the task when running a more time consuming operation.
4.Other hardware
Cause.
Computer automatic shutdown solution:
1. First check the hardware is not a problem, focus on the motherboard, CPU fan, host power supply, power outlets are not a problem.
2. Check if there is some application software task is completed after the shutdown is enabled. This can be clearly seen. The characteristic is that before the shutdown, there will always be a program running, and a dialog box will be prompted to remind you to shut down.
3. Solve the virus Trojan and repair the damaged files of the system. Use the latest version of Kingsoft Internet Security 2011 to complete virus removal and system configuration repairs at one time. "
First, the CPU load is too large, or the work is not normal. Check the CPU and graphics card heat, dust, oil, or replace the fan.
Second, the power supply voltage Unstable, power supply is insufficient. Replace high-quality power with high power.
Three, often clean the disk and defragment the disk.
1. In the "My Computer" window, right click The drive letter to be cleaned - "Properties" - "Clean Disk" - check the file to be deleted - OK - Yes.
2. Clear the temporary file, start - run - enter "%temp%" - OK
3, use the optimization master or super rabbit to clean up the registry and junk files.
4, close some startup programs, start-run-msconfig---start, except anti-virus software, input General procedures can be turned off.
5, delete unused program software.
6, defragmentation of the disk - start - all programs - attachments - system tools - - Disk Defragmenter - Selected Disk - Analysis - Defragmentation.
7, to reduce the memory burden, open the program can not be too much. If you play at the same time Too many documents or too many programs are running, there is not enough memory to run other programs, you should close unused programs and windows at any time.
4. Upgrade the graphics card, network card driver, and change the graphics card with higher grade.
Five, increase physical memory, now the memory is generally at least 2G.
Six, reasonable settings virtual memory.
1, play game
The virtual memory can be set larger. The maximum and minimum values are set to 2-3 times of the physical memory. If it is too large, it takes up too much hard disk space.
2. The virtual memory setting method is: Right Hit My Computer - Properties - Advanced - Performance Settings - Advanced - Virtual Memory Changes - Select the partition in the drive list to select the virtual memory (page file) - custom size - in the "initial size" and Set the value in "Maximum", then click the "Settings" button, and finally click the "OK" button to exit. 3. The virtual memory (page file) is stored in the partition, there must be enough space, the hard disk resources are insufficient, resulting in virtual Not enough memory, in one computer, in one Setting virtual memory is enough, you don't have to set it in multiple partitions. 7. Optimize the computer with optimization master, 360 or super rabbit.
Going to the computer store to do the system, you can make your computer faster and pick up some garbage. But useful files should be backed up.
You can also scan the Trojan virus
< Br> CPU overheating will automatically shut down, check with Lu master, if so, you can remove the CPU radiator to clean up the dust, re-coated thermal grease, if it is invalid, replace the CPU radiator.
It may be that the heat is not good
1. The computer card is slow or unable to shut down normally or shuts down slowly or the virtual memory is small
The following methods can also increase the speed of the computer
In the start menu Enter msconfig to enter, in the boot all (except ctfmon) checkmarks are removed to save the restart try (can speed up the startup speed), generally you start too much running, or file conflicts
install 360 security guards Boot has been pressed F8 to enter the safe mode to kill, now nine of the ten poisons on the Internet are Trojans, so the anti-virus software can not find the poison, it is recommended to install 360 to kill
2. Crash, generally running too much software, Or the computer is not good at heat dissipation, it is too hot, the CPU fan is replaced, or the memory is not compatible.
In the start menu, enter msconfig and enter. In the startup, all the (except ctfmon) checkmarks are removed and saved. Try restarting (you can speed up the startup). Generally, you start too much, or file conflicts. Problem
Install 360 security guards, boot has been pressed F8 into safe mode to kill, now nine of the ten poisons on the Internet are Trojans, so anti-virus software can not find poison, it is recommended to install 360 to kill
heat is not good Reinstall the CPU heat sink and graphics card fan, you can contact badly, you can replace the CPU fan
Replace the memory
3. The blue screen is generally too hot for the CPU, dust, viruses, bad sectors of the hard disk, memory quality problems
Enter msconfig in the start menu run, enter all the (except ctfmon) checkmarks in the boot and save the restart (try to speed up the startup), generally you start too much, or file conflicts
Install 360 security guards, boot has been pressed F8 into safe mode to kill, now nine of the ten poisons on the Internet are Trojans, so the anti-virus software can not find the poison, it is recommended to install 360 killing
heat is not good, heavy Install the CPU heat sink, may be in poor contact, replace the CPU fan
Replace the memory, or clear the dust on the memory
If you find a hard disk crash, the blue screen, the hard disk has bad sectors
4 Unreasonable restart, generally the CPU is too hot, virus, dust, power is not good, memory is not good, the graphics card is too hot, the motherboard capacitor is not good
Enter msconfig in the start menu run, enter all in the boot (except Ctfmon) check all the hooks to save the restart try (can speed up the startup speed), generally you start too much running, or file conflicts
install 360 security guards, boot has been pressed F8 into safe mode to kill, now Nine of the ten poisons on the Internet are Trojans, so the anti-virus software can not detect the poison, it is recommended to install 360 to kill.
