Option 1: 1. There is a virus in the computer. Press F8 to enter safe mode. Use Tencent Computer Manager, Kaspersky and other anti-virus software to scan the computer comprehensively and clean up the virus.
2. Turn off network wake-up. Right-click the computer (My Computer) on the desktop-Properties-Device Manager-Expand the network card-Right-click the network card-Properties-Advanced-set "Turn off network wake-up" to turn off power management-uncheck "Allow the computer to turn off this device to save power".
3. Set the system error function. Right-click on My Computer-Properties-System Properties Advanced-Startup and Recovery-Settings-Startup and Recovery-and remove the "Automatic Restart" option in the "System Failure" column.
4. The memory may be damaged or poorly contacted, or there is something wrong with the motherboard memory slot. Clean the memory slot with alcohol or an eraser and replace the suspected memory. Option 2: 1. When we turn on the computer, we can always press our F8 to enter the safe mode, and then we will enter the next operation.
2. You can use the up and down keys on the keyboard to adjust and select the "Last Correct Configuration" option, and then press Enter to enter our system. 3. Then put it into the CD of the system, set the CD as a direct startup item, and press the del key of the keyboard when the computer is turned on. 4. When you hold down F8, you can choose the optical drive to start the computer, and you will enter the optical drive settings of the system.
5. Press 1 to install the system E799Be5BaA6E78988E69D8331331323035 to connect the C disk of the computer. After selecting it, you can wait for the installation and restart the computer.
2. What if the desktop computer restarts frequently and automatically?
What were you doing when the computer was restarted? Can you tell me something? I will give you a more accurate answer according to what you said.
Please describe in detail the performance of your computer before restarting and your operations, which may have caused the restart. Ask me if you have any questions (I will answer you again according to the information you provided).
Restart is usually caused by your own incorrect operation. Remember not to do anything that will easily lead to a restart. Don't operate the computer at full load, that is, when playing games, watching videos, downloading and watching web pages, it is most likely to restart, crash and blue screen when doing other operations, so don't operate other things when playing games, watching videos, downloading and watching web pages.
No matter what you are doing, as long as there is a sign of a card, stop what you are doing and quit the test, so that it will not be restarted. If it's still like this, don't play or watch.
In terms of hardware, the high temperature of CPU and other hardware is caused by insufficient memory, broken hard disk, unstable voltage and unsuitable existing hardware.
Win78 can basically run 4G memory, XP is 2G memory, and it is best to double it. If you don't use this number, it is recommended to add more memory (this is a practical number, not a theoretical number).
3. What if the computer is always on and off?
The solution is as follows:
1. First of all, if the computer presses the power button, all the signal lights will still light up and the screen will light up. We can be a little lucky that the computer has only software problems, not hardware problems.
2. The software problem that can make the computer restart constantly may be that the computer is infected with a virus or the system file is damaged. There are two most direct solutions to software problems.
3. The first solution is to press the F8 key when starting the computer, enter the safe mode of the computer, and select "Last Correct Configuration".
(If you are not sure when to press F8, you can hold down the power button and press F8 until the interface as shown in the figure appears. )
4. If the first method doesn't work, or if you can't enter the interface shown above after pressing F8, then the simplest and rudest solution is to reinstall the system and find a system CD. If there is no system CD, the most thorough way is to restore the computer to the factory settings. Different notebooks and computers have different ways to restore the factory mode, so I won't go into details here.
Hardware problem
1, there are many kinds of hardware problems that cause the computer to restart constantly, such as insufficient power output, too high CPU temperature, damaged cache, loose graphics card and so on;
2. For hardware experts, you can disassemble the computer yourself and find out the problem;
If you are not an expert, you'd better have your computer repaired.
4. Why does the desktop always restart repeatedly?
Hello! !
There are many reasons why the host computer can't be opened.
Among them, the faults that ordinary families can solve are.
One. Memory is loose. Causing the self-test to fail. . One more insertion will solve this problem.
Two. The graphics card is loose, and the self-test cannot correctly identify it. You can also solve this problem by inserting it again.
Three. The data cable connection between the monitor and the graphics card is incorrect. Such a fault phenomenon is to display a prompt: no signal. People mistakenly think that the host is not turned on.
Yes In fact, if you see such a prompt appear. Then connect the video card and monitor directly.
Note: When plugging and unplugging again, it is best to wipe the golden finger (that is, the interface) with a rubber, which can improve the chance of repair.
The problem that ordinary families can't solve is:
One. The power supply is damaged.
Two. The motherboard is damaged.
Three. Memory and graphics card are damaged (note: looseness and damage are two principles, one is just poor contact. The other is that the hardware itself has failed. such
This situation cannot be solved by re-plugging. )
5. What if the computer restarts repeatedly?
I usually encounter the following situation when restarting. I don't want you to have a look, which may give you some inspiration.
1. virus, virus removal, Trojan horse. 2. Check whether the CPU temperature is too high, which often leads to a protective automatic restart.
Dust, oil or replace the fan with a new one. 3. The city voltage is unstable and the chassis power supply is insufficient. When running large-scale 3D games and other software that take up a lot of CPU resources, when the CPU needs high power supply, the power supply is not enough and overload causes the power failure protection to restart.
Replace the power supply of high-quality and high-power computers. 4. Poor thermal stability of the memory, chip damage or wrong setting will also lead to restart.
Replace the memory. 5. The integrated graphics card and sound card conflict with the added independent graphics card and sound card, resulting in a restart.
Shield the integrated graphics card and sound card that comes with the motherboard. 6. The graphics card and network card are loose, and the parallel port, serial port and USB interface will automatically restart if they fail or are incompatible.
Insert tightly and replace. 6. The system file is destroyed, and the system will be forced to restart when it is started.
Cover the installation or reinstall.
6. What if the desktop computer starts automatically?
There are two main reasons for the failure of computer optional boot:
1.BIOS setting is incorrect. When the timed start function is set to enable, the machine will automatically start at a specific time on the set date. In addition, some motherboards have automatic boot function in BIOS settings. If this function is selected, the machine will be turned on automatically after turning on;
2. Hardware failure, or the power supply itself has poor anti-interference ability, or the voltage is too low, the signal quality from the motherboard may be poor. These problems can be solved by replacing the power supply.
You can check the settings of the machine as follows.
1 Check the BIOS settings, and set the restoration of AC power failure in the power management settings to disabled in the BIOS.
2 If the above method doesn't work, continue to set the APM of power management setting as PM control to Yes in BIOS.
