This article mainly explains "what is the emergency treatment of common computer problems". Interested friends might as well take a look. The method introduced in this paper is simple, fast and practical. Next, let the editor take you to learn "what is the emergency handling method for common computer problems?"

1. Boot system self-test

Phenomenon analysis: this is caused by a sudden power outage or forced shutdown. The voltage fluctuation caused by the moment of power outage will impact the chips, circuits, resistors and so on of computer hardware. Once you are doing disk reading and writing when there is a power outage, it is possible to produce bad channels, or when you are writing a manuscript, the data will be lost.

Countermeasures: when equipped with a computer, choose a brand power supply, which can minimize the adverse impact of voltage fluctuations on the hardware. After a power outage, turn off all power supplies to prevent the monitor and part of the ATX power supply from starting at the same time when the next call comes, which will cause bad damage to the hardware. When you edit a document with WORD, use the auto-save feature of WORD. If you happen to be operating on the disk at the moment of the power outage, it is recommended that you do not skip disk detection at startup next time to see if there is any bad path. Once a bad road is found, use NORTON,PQMAGIC and other tool software to repair or shield the bad road. In addition, if you are financially permitted, it is recommended to choose a UPS to provide power-off protection for the computer for a period of time.

two。 Automatic shutdown

Phenomenon: the computer suddenly shuts down or restarts the system automatically during normal operation.

Phenomenon analysis: today's motherboard has a temperature monitoring function for the processor. Once the processor temperature is too high and exceeds the temperature set in the motherboard BIOS, the motherboard will automatically cut off the power supply to protect the relevant hardware. On the other hand, the power management and virus software in the system will also cause this phenomenon.

What should be done: if the above sudden shutdown phenomenon continues to occur, first make sure that the heat dissipation of the processor is normal. Open the chassis to see if the fan blade is working properly, and then enter the BIOS option to see the speed of the fan and the operating temperature of the processor. If it is found that it is the problem of the fan, carry on the related dedusting maintenance of the fan or replace a better quality fan. If you rule out the hardware, enter the system, re-cover the installation of power management, and then thoroughly check and kill the virus. When these factors are excluded, the cause of the problem may be the aging or destruction of the power supply, which can be confirmed by replacing the power supply. If the power supply breaks down, it will be replaced with a new one. It must not continue to be used, and the hardware will be burned.

3. System crash

Phenomenon: the desktop is locked, the mouse can not move, even hot start (ALT+CTRL+DEL) is not allowed in serious cases. And then there is the blue screen phenomenon.

Phenomenon analysis: the BUG of the system itself and the compatibility between the software are the cause of the problem, or it may be that the user runs too many large programs at the same time, resulting in process blocking and jam.

Countermeasures: there are two kinds of deadlock, real death and fake death. The easiest way to distinguish between the two is to press the Numlock key in the keypad area to observe whether the indicator light has changed. If you have, you will fake your death; on the contrary, you will really die. Fake death can simultaneously press ALT+CTRL+DEL to select the program name in the task list that appears, mark the items that do not respond, and click to end the task. Damn it, only the cold start. For the blue screen, after pressing the ESC key is invalid, select restart and press the reset key on the chassis panel. Compatibility issues can be solved by uninstalling the "problem" software and updating the motherboard BIOS and related motherboard drivers.

4. Virus attack

Phenomena: slow operation of the system, panic, illegal operation, flashing hard disk lights, frequent blue screen, and inexplicable system hints.

Phenomenon analysis: virus is essentially a malicious computer program code, virus through a large number of self-replication, while secretly running in the system, occupy system resources, serious damage to software and hardware, such as CIH, hard disk lock and so on.

Countermeasures: as virtue rises one foot, the devil is one foot low, the nemesis of the virus is antivirus software. Once you suspect that your machine is infected with a virus, please restart the system to DOS and run the genuine antivirus software (DOS version) so that you can kill the virus that cannot be killed under windows; then boot to the system desktop and run the version of the antivirus software windows to kill the virus again. On the other hand, because some files will be destroyed when the virus is serious, we back up the important files to a drive other than disk C before the virus breaks out, and set the properties of the data files to read-only. At the same time, we should always update the antivirus software virus library, reduce the use of pirated discs, Internet-loving friends do not download unknown email attachments.

5. System problem

Phenomenon: can not enter the system, the typical performance is to pass the post, stop at the startup screen, or display: The disk is error and many other phenomena prompted by E text.

Phenomenon analysis: this is a system problem, which can be caused by many reasons, the more common is that the system file is modified, destroyed, or loaded with abnormal command line. In addition, the problem with the hard drive is also one of the reasons. What to do: first try whether you can enter safe mode, press F8 to boot, and select the third item in the startup menu: Safe model (safe mode). After entering safe mode, you can find the problem through the device manager and the system file checker. No. Can find out the body and then determine whether the del or setting interrupt. You can also reinstall the driver, and the damaged system files can be recovered from the installation files (it is recommended to copy the windows installation disk to the hard disk in advance). If you can't even enter the safe mode, boot to DOS with a booted CD or floppy disk, first kill virus under DOS and use Dir to check whether the system files in disk C are complete or not. If necessary, you can use the system floppy disk to perform Sys CDir to restore the relevant basic system files. If no files are found on disk C, the system will have to be completely reinstalled.

6. Drive loss

Phenomenon: the desktop resolution is not normal when booting, and the audio file shows that the "XXX" device is being occupied. Phenomenon analysis: after excluding the cause of the virus, this phenomenon often occurs on the old machine that has been used for N months, or the user has recently moved the parts in the host computer, such as graphics card and computer I card, which may cause poor contact with the hardware. as a result, the system has not thoroughly detected the relevant hardware.

The solution: reinstall the driver of the video card and check whether the relevant accessories are in full contact with the motherboard: one is to ensure the cleanliness on the golden fingers of the video card and sound card, and the other is to insert it properly when inserting it into the relevant slots, and then connect to the matching speakers and monitors. If necessary, you can change the slot position of the computer I card to avoid resource conflicts with the graphics card.

7. Boot black screen

Phenomenon: boot black screen, no display, there may be an alarm sound.

Phenomenon analysis: poor contact between hardware, or hardware problems, related hardware involves memory, graphics card, processor, motherboard, power supply and so on. The boot of the computer should be powered on by the power supply, then by the BIOS of the motherboard to guide the self-test, and then through the processor, memory, graphics card, etc. This process is reflected on the screen called self-test, first through the graphics card BIOS information, then motherboard information, and then memory, hard disk, optical drive and so on. If something goes wrong in the middle of this, the computer will not be able to start normally, or even the black screen.

Countermeasures: first of all, make sure that the external and internal connections are smooth. External connections include monitor, mainframe power supply and so on. There is an internal connection between the mainframe power supply and the mainframe power interface (sometimes poor contact here). The more common reason is: graphics card, memory due to the use of too long, long-term contact with the dust in the air, resulting in oxide layer on the gold finger, resulting in poor contact. In this regard, wipe the golden finger back and forth with moderate alcohol on the cotton and insert it back after it dries. In addition, observe whether the processor is working properly, turn it on for about half a minute, and touch the heat sink of the processor fan with your hand to see if there is a temperature. If there is temperature, the possibility of processor failure can be basically ruled out. Tidy up the processor socket without temperature to make sure the contact is in place. After that, there is no temperature, and your processor can be upgraded: (in addition to the above, there is another must-kill: remove the BIOS setting by unplugging the jumper or replace the CMOS battery on the motherboard. When all of these methods have been tried and failed, you can summon a computer doctor to make house calls.

8. Strange sound and strange smell

Phenomenon: hear a strange noise or smell a strange smell.

Phenomenon analysis: strange noise, may be due to the bad path of the hard disk caused by the hard disk (grid shrill sound); it may also be the hard disk, the optical drive screw is not fastened, causing the resonance of the chassis. Peculiar smell, mostly burnt smell, very prickly kind.

The solution: turn off the power first. If there is a strange noise, open the chassis panel and check one by one. If it is bad, repair or shield it. Be careful with odors. At this time, smell with your nose, find the smelly parts, and then unload them to the computer company to deal with, in which everyone must defend their own consumer rights and interests. Those that have not passed the warranty period-those that should be replaced, those that should be repaired.) This must not be careless! So if you smell a strange smell, immediately cut off the power supply, and then open the chassis to find the reason.
