In the process of the use of computers will inevitably meet a lot of unexpected failures, the causes of these failures may be caused by software, or it may be caused by hardware failure, or other factors that … … Well, our primary computer users how to deal with these events should do, see below:
Suffered blackouts

Analysis: This is suddenly “fail” result. By the instantaneous power generated by the impact of voltage fluctuations in the computer hardware chips, circuits, resistors and so on. Once the power of disk to read and write when you are operating, there may have Bad Track, or when you are in the preparation of manuscripts, then the data will be lost … …
Strategy should be: with the computer matching of brand power, this will maximize the decrease from the power supply voltage fluctuations on the adverse effects of the hardware. After power failure, turn off all power to prevent the next call when the ATX power supply monitors and some start at the same time, this would result in undesirable damage to hardware. When you edit the document using WORD, the WORD to use the automatic save function. If the power of the moment happens to your disk to operate in, we recommend that you do not start the next boot when the disk to skip detection, detection of whether or not arising from Bad Track. Once a Bad Track, used NORTON, PQMAGIC software and other tools to repair or shielding Bad Track. In addition, if you permit the economy, the proposed placement of a UPS, the computer power to provide protection for some time.
Automatic shutdown
Phenomenon: the normal operation of the computer process, a sudden self-closing system or reboot the system.
Analysis: Today’s motherboard to monitor CPU temperature, once the CPU temperature is too high, more than the motherboard’s BIOS settings in the temperature, the motherboard will automatically cut off power to protect the hardware. On the other hand, the power management system and virus software will also lead to the occurrence of this phenomenon.
Strategy should be: If the above-mentioned phenomenon of the sudden shutdown has occurred, make sure whether it is normal for CPU cooling. Visual open chassis fan blades are working properly, and then enter the BIOS options to see the fan speed and CPU temperature. Found to be fans of the problems related to the fan for maintenance or replacement of the dust fan of better quality. If the reasons for exclusion of the hardware into the system, from the “kissed to death,” the installation CD-ROM covers the installation of power management, and then killing the virus completely. When these factors are excluded, the failure may be the cause of aging or damaged power supply, which can be adopted to confirm the replacement of the power law, broken power supply on another new, must not continue to use, the hardware will be destroyed
System crash
Phenomenon: the desktop is locked, the mouse can not move, even the serious hot-start (ALT + CTRL + DEL) will not work. Phenomenon there is a blue screen.
Analysis: “kissed to death,” the system as well as their own BUG software compatibility problem is the failure, or it may be the user running the same time too many big procedure, resulting in the process of obstruction caused a crash.
Countermeasures: When two kinds of sub-machine, real and fake as when two distinguish between the most simple way is to press the small keyboard Numlock key area to observe any changes in its light. There are, then leave when; the other hand, when true. Leave at the same time when pressing the ALT + CTRL + DEL the task in the list were selected after the tagging procedure did not respond to the item, click End Task. True when only a cold start. The blue screen, press the ESC key is invalid, choose to restart, according to chassis reset button on the panel. For compatibility issues, you can uninstall from the “problem” of software and update the motherboard BIOS and motherboard drivers to resolve.
Virus attack
Phenomenon: the system is running slow, crashes, illegal operation, the hard disk light flash disorder, often a blue screen, as well as baffling prompted … …
Analysis: in essence, is a virus, malicious computer code, the virus through a large number of self-replication, at the same time hidden in the system operation, possession of system resources, but also serious damage to software and hardware, such as the CIH, such as hard disk lock .
Countermeasures: rules, magic low, the virus is the nemesis antivirus software. Once the suspect’s own machines infected with the virus, restart your system to DOS, run a genuine copy of antivirus software (DOS version) This will kill the “kiss to the death” of the virus can not kill; and to the system desktop and then start running anti-virus WINDOWS version software antivirus again. On the other hand, due to severe virus attack will destroy a number of documents; we will attack the virus before the backup of important documents to a disk other than C drive, and the data file set to read-only attribute. At the same time, you should always virus database update antivirus software, the use of pirated CDs, available on the Internet for unidentified friends of the e-mail attachments do not download.
System failure
Phenomenon: we can not join the system, a typical example for the power-on self test is passed, stop in the start screen, or display: The disk is error, such as the number of E is the text prompt.
Analysis: This is the system failure may be caused by many reasons, is the more common system files are modified, damaged, or abnormal loading of the command line. In addition, the hard drive is also one of the reasons for the failure.
Countermeasures: First of all, whether to try to enter Safe Mode, press F8 key to boot, select the Start Menu in the third: Safe model (safe mode). After entering Safe Mode, Device Manager can be and the System File Checker to find fault, to have “!” Issue can be identified and then traveling abroad or set up to determine whether disruption of del. Can also be re-driver damaged system files to restore from the installation files (recommended prior WINDOWS put the installation disk in the hard disk copy). If Safe Mode can not enter through with the CD-ROM or floppy disk to start boot to DOS, the DOS under the first use of Dir to check anti-virus and disk C’s system files is complete, if necessary, can be carried out through the system floppy disk Sys C:, the restoration of basic system files. If C did not find paper tray, only to completely reinstall the system.
Driver missing
Phenomenon: when the 16-color boot display, release the audio files show the “XXX” equipment is being occupied.
Analysis: the reasons for exclusion of the virus, this phenomenon occurred in the used N-month-old machine, or users recently had a host of components, (such as graphics cards and PCI cards), it may cause the hardware poor contact, resulting in the complete system does not substantially related to the hardware detected.
Countermeasures: to re-install the graphics drivers, and check-related accessories and full access to the motherboard: The first is to ensure that graphics cards, sound cards, Goldfinger’s clean, and the other is inserted into the relevant slot of its force when appropriate, to Insert can be quasi-vertical, with the draw with the connection of the speaker and display. If necessary, replace the PCI card slot location, to avoid resource conflicts and generate graphics.
Black boot
Phenomenon: boot black, does not appear, there may be sound alarm.
Analysis: poor contact between the hardware, or hardware failure, related to the hardware involved in memory, video card, CPU, motherboard, power supply and so on. Boot the computer through the power supply first, and then guided by the motherboard BIOS self-test, and then through the CPU, memory, graphics and so on. This process is reflected in the screen is called self-test, first through the video card BIOS information, and then the motherboard information, then memory, hard drives, CD-ROM, etc.. If this is a problem out of the middle of which, the computer will not start correctly, or even black.
Countermeasures: first to confirm the external connection and internal connection is to connect smoothly. External monitor connection, power supply, such as the host. Host internal power supply and the host interface to connect (sometimes bad here). The more common reasons are: graphics cards, memory as a result of the use of excessively long hours, and air in the long-term exposure to dust, causing the oxide layer golden finger, resulting in poor contact. In this regard, with moderate alcohol glue cotton cloth Finger back and forth, to be inserted after the stem back. In addition, observe the CPU is working properly, the boot about half a minute, hand-to-CPU heatsink fan is temperature. Temperature, the CPU can be broken the basic rule out the possibility. Temperature did not click on the finishing of the CPU socket, to ensure that the contacts in place. Not after that temperature, you can upgrade the CPU on the: (In addition to the above methods, there is still one way: jumper out the method used to remove or replace the motherboard BIOS settings of the CMOS battery. When these methods are tried and all fail, you can call out of the mountains to help the Colombian shrimp.
Sound strange smell
Phenomenon: to hear sound or smell strange odor.
Analysis: strange ring, may be caused as a result of the hard disk drive Bad Track issued (the ear-piercing voice chattered); is also possible that the hard disk, CD-ROM is not on the prison screws, resulting in the resonance box. Smell, most probem, it is the kind of sub-pungent.
Countermeasures: First of all, turn off the power. If the strange sound, then open the case panel, one by one to check, if the Bad Track, then repair or shield. For the smell, it is necessary to be careful. Then use your nose sniff to find the odor components, and then unloaded to the computer company to deal with, in this intermediate, we have to defend their rights and interests of consumers. (Did not have the warranty – for the change of the revised amendment.) Shall not effect the millions! Because, the author of the Onda drive after the smell is less than power (slow N seconds) to the driver chip burned alive (Firewall), and then use the money to find there is no way Uncle JS. (So if you smell the smell, immediately cut off power supply, chassis and then look for the following reasons, however, tens of millions display can only be handed over to professionals for repairs, there are high-voltage, and tens of millions of their own lives joke.
