In the normal use of the computer process, will inevitably encounter a lot of sudden failure, the cause of these failures may be the cause of the software, may also be caused by hardware failure, or other factors ... So, here's what I'll tell you about common troubleshooting methods:

One, suffered a power outage

Phenomenon: The computer in the normal course of operation, suddenly automatically shut down the system or restart the system.

Phenomenon Analysis: Today's motherboard on the CPU temperature monitoring function, once the CPU temperature is too high, more than the motherboard BIOS set the temperature, the motherboard will automatically cut off the power to protect the related hardware. On the other hand, power management and virus software in the system can also cause this phenomenon to occur.

Should be the strategy: the above sudden shutdown phenomenon, if it has occurred, first of all, to determine whether the CPU cooling normal. Boot box Visual fan blades are working properly, and then enter the BIOS option to see the fan speed and CPU operating temperature. The fan is found to be the problem, the fan is related to dust removal maintenance or replacement of better quality fans. If you exclude the cause of the hardware, enter the system, from the "Kiss to Die" installation of the CD-ROM to cover the installation of power management, and then completely kill the virus. When these factors are excluded, the cause of the failure may be the power of aging or damage, this can be replaced by the power supply method to confirm that the power is broken off to change a new, must not continue to use, will burn the hardware

Second, the system as a machine

Phenomenon: The desktop is locked, the mouse can not move, serious even hot start (Alt+ctrl+del) are not. There is a blue screen phenomenon.

Phenomenon analysis: "Kiss to Death" system itself bugs and the compatibility between the software is the cause of the failure, it may be the user at the same time too many large programs run, resulting in process blocking, causing the machine.

Coping strategy: When the machine is divided into 2 kinds, true and false when, the most simple way to distinguish between the two is to press the keypad area of the NumLock key, to see if the light has no change. If there is, it is false; If you can press Alt+ctrl+del at the same time select the program name in the list that appears, and then mark the item that does not respond, click End Task. Really when, only cold started. For blue screen, when the ESC key is pressed, select reboot and press the reset button on the chassis panel. For compatibility issues, you can remove the issue software and update the motherboard BIOS and related motherboard drivers.

Iii. Viral Seizures

Phenomenon: System running slowly, when the machine, illegal operation, hard drive lights flashing, often blue screen, as well as inexplicable wonderful system tips ...

Phenomenon Analysis: The virus is essentially a malicious computer program code, the virus through a large number of its own replication, while in the system secretly run, occupy the system resources, serious will also cause damage to software and hardware, such as CIH, hard drive locks.

Coping strategy: Villains, Magic Low one Zhang, the bane of the virus is anti-virus software. Once you suspect that your machine infected with the virus, please reboot the system to DOS, run the genuine anti-virus software (DOS version) so that you can kill the "kiss to Death" under the virus, and then boot to the system desktop, running antivirus software version of Windows to antivirus. On the other hand, it destroys some files because of the severity of the virus attack, and we back up the important files to the other drives outside the C disk before the virus attack, and set the properties of the data file to read-only. At the same time, we should always update anti-virus software virus library, less use pirated discs, has been on the internet Friends of unknown mail attachments do not download.

Iv. system failure

Phenomenon: Can not enter the system, the typical performance of the post through, at the start of the screen stop, or show: Thediskiserror and so on have e-wen prompts many phenomena.

Phenomenon Analysis: This is a system failure, can be caused by a number of reasons, the more common is the system files are modified, damaged, or loaded the abnormal command line. In addition, the failure of the hard drive is also one of the reasons.

Coping strategy: First of all to try to enter Safe mode, boot press F8 key, select the launch menu of the third item: Safemodel (Safe mode). After entering safe mode, the Device Manager and the System File Checker can be used to find the fault and encounter the "!" The number can be ascertained to determine whether the Del or setting is interrupted. You can also reload the driver, and the system file may be damaged from the installation file (it is recommended that you copy the Windows installation disk to the hard drive beforehand). If you can not enter the Safe mode, you can boot to the CD or floppy disk to start to DOS, the first anti-virus in DOS and with DIR check C disk System file is complete, if necessary, through the system floppy disk for SYSC:, restore related basic system files. If no files are found in C disk, only the system is completely reload.
