When we use the computer, we often encounter the situation that the computer can't enter the system after booting, and it keeps restarting. This gives the rookie no chance to solve it. So why does the computer keep restarting ? What should I do if the computer keeps restarting? Let's take a look at the decoration home decoration network Xiaobian. What should I do if the computer keeps restarting? Â Why the computer keeps restarting - software reasons: 1, virus damage: Computer viruses have emerged since the computer was in place. More typical is the "shock wave" virus that causes serious damage to the global computer . The attack will also prompt the system to start automatically after 60 seconds. In fact, as early as the DOS era, there are many viruses that can automatically restart your computer. For virus damage, we can use the latest version of anti-virus software for anti-virus, generally found that the virus exists. Of course, there is also a possibility that someone has maliciously invaded your computer while you are on the Internet, and placed a Trojan horse program. This way the other party can remotely control all activities of your computer, including of course, to restart your computer. For some Trojans, it is not easy to remove, it is best to reinstall the operating system. 2, the system file is damaged: When the system file is destroyed, such as KERNEL32.DLL under Win2K, the font below the Win98 FONTS directory, etc., the basic file is destroyed when the system is running, and the system will not be able to complete initialization and force restart when it starts. You can do a test and rename the font "FONTS" in the WIN98 directory. When you turn it on again, our computer will continue to restart. For this type of failure, because you cannot enter the normal desktop, you can only overwrite or reinstall. 3. The timing software or scheduled task software works: If you set up a reboot or load some work programs in the Scheduled Taskbar, the computer will start again when the time comes. In this case, we can open the "Start" item, check whether there are any implementation files or other timed work programs that are not familiar to them, and then block them and then turn them on. Of course, we can also directly enter the "Msconfig" command in "Run" to select the startup item. Why the computer keeps restarting - hardware reasons: 1, the voltage is unstable: The switching power supply of a general household computer operates at a voltage range of 170V-240V. When the mains voltage is lower than 170V, the computer will automatically restart or shut down. Because of the fluctuations in the mains voltage, we sometimes don't feel it, so we mistakenly think that the computer is inexplicably restarted automatically. For areas with frequent power supply instability, we can purchase UPS power or 130-260V wide-amplitude switching power supply to ensure stable operation of the computer. 2, the quality of the cable or power outlet is poor, poor contact: It may be the wall socket used in our home. Most wall sockets are not installed professionally, so the wiring inside the socket is very non-standard. Especially these sockets can easily cause internal heating if we use high-power electric heaters frequently. The oxidized virtual connection forms an intermittent power failure, causing the computer to restart or the display to blink. For the problem of whether it is a virtual connection inside the wall socket, we can try to change the host to a wall socket to see if there is the same automatic restart problem. 3. The power of the computer power supply is insufficient or the performance is poor: This situation is also more common, especially when we add new equipment to our host, such as replacing the high-end graphics card, adding a recorder, adding a hard disk, it is very easy to appear. When the host works at full speed, such as running a large 3D game, recording at high speed or preparing to read the disc, when the dual hard disk is copied, the data may be stopped due to insufficient power supply of the instantaneous power supply, but due to After the power supply stops outputting, the load is relieved and the power is turned on again. Because the recovery time after protection is very short, the performance given to us is that the host automatically restarts. 4. The mains plug of the main switch power supply is loose and the contact is poor: In this case, most of them will appear on the DIY machine. The power cord of the host power supply is not certified by 3C and is not compatible with the power socket. When we shake the table or touch the host, the host will automatically restart, usually accompanied by a slight electric slamming sound. Replace the high-quality 3C certified power cord. 5, the motherboard power supply ATX20 socket has a virtual solder, poor contact: This kind of fault is not common, but it does exist. It is mainly when the host is working normally. Move the ATX20 pin plug left and right to see if the host will restart automatically. At the same time, check the reed inside the 20-pin power plug for oxidation. This can easily lead to large contact resistance and poor contact, causing the host to freeze or restart. Sometimes it is necessary to check the connection line of the 20-pin plug tail, whether it is secure. If it is the solder joint of the motherboard, it can be repaired directly with an electric soldering iron. Note: When soldering the computer board such as the motherboard, hard disk, graphics card, etc., be sure to ground the soldering iron well or unplug the power cord during soldering. If it is a power problem, it is best to replace a good power supply. 6, CPU problem: Some internal CPU functions are damaged. When the L2 cache is damaged, the computer can also be started. It will even enter the normal desktop for normal operation. However, when a special function is performed, it will restart or crash, such as drawing a table and playing VCD. Play games and more. Try to mask the L2 cache (L2) or L1 cache (L1) in CMOS to see if the host can run normally; no longer just replace it with a good CPU. If it works properly after being shielded, it can still be used. Although it is slower, it will save money. 7, memory problems: If a chip is not completely damaged on the memory stick , it is likely to pass the self-test (mostly POST is set), but it will restart unexpectedly due to the failure of the function due to the large amount of heat generated by the memory. Most of the time, when the memory is damaged, the opportunity alarm is issued, but after the memory is damaged, there is no alarm, and the fault that is not powered is still there. It is best to use the exclusion method to quickly identify the fault location. 8, the optical drive problem: If the internal drive is damaged, it will cause the host to start slowly or fail to pass the self-test, or it may restart suddenly during the work. For the latter case, if it happens after we replace the optical drive, it is likely that the power consumption of the optical drive is different. What everyone needs to know is that although the ATPI interface of the optical drive is the same, the pin definitions of different manufacturers are different. If there is a problem with our hard disk cable, there may be no problem with the use of a certain brand of optical drive, but for other The brand CD-ROM drive can not work, this requires everyone's attention. 9, RESET button quality problems: If the RESET switch is damaged and the internal reed is always in the shorted position, the main unit cannot be powered on. However, when the RESET switch is weakened or the button on the chassis is pressed and it is not easy to bounce, it will appear during use, because the occasional touch of the chassis or under normal use and the host suddenly restarts. Therefore, when the RESET switch cannot be pressed freely, we must check it carefully. It is best to replace the new RESET button switch or apply lubrication to the external button of the chassis. 10. Automatically restart when accessing the network card or parallel port, serial port, or USB interface to access external devices: This situation is generally caused by external faults, such as the parallel port damage of the printer, short-circuit of one foot to the ground, short-circuit of the USB device to the ground, non-standard work of the network card, etc. When we use these devices, it will be due to sudden power supply. A short circuit causes the computer to restart. Why the computer keeps restarting - other reasons: 1. Poor heat dissipation or temperature measurement failure: The CPU has poor heat dissipation. The problem that often occurs is that the CPU heatsink clips are off. There is a foreign object between the CPU heatsink and the CPU. When the CPU fan is used for a long time, the heat sink is too dusty. These conditions will cause the CPU to dissipate heat and accumulate. The temperature is too high and automatically restarts. There is also damage to the temperature probe under the CPU or damage to the temperature measurement circuit inside the P4 CPU. The BIOS on the motherboard has a BUG under certain special conditions, which will cause the host to automatically restart during the working process. Finally, the CPU protection temperature set in CMOS is too low, which will cause the host to restart automatically. 2, the fan speed failure: When the speed measuring circuit of the CPU fan is damaged or the speed measuring line is intermittently disconnected, the motherboard will automatically shut down or restart because the fan does not detect the speed of the fan. However, we may see that the CPU fan is rotating normally and the speed is measured. Also normal. 3. Strong magnetic interference: Don't underestimate the electromagnetic interference. Many times our computer crashes and restarts because of interference. These interferences are caused by internal CPU fan, chassis fan, graphics card fan, graphics card, motherboard, hard disk, and external power line. , inverter air conditioners and even large equipment such as automobiles. If the interference performance of our host is poor or the shielding is poor, the host will restart unexpectedly or crash frequently. The above is what Xiaobian brought to you.
