【 Weak current college 】 computer failure judgment (6)

Misoperation and application class failed
First, define an example

Such failures are mainly refers to start before the shutdown after the application and system failures.

Second, the possible failure phenomenon

1. does not wake up after sleep;

2. the system runs in a blue screen, panic, illegal xx for symptoms such as;

3. the system runs slow;

4. run a certain application, leading to failure of hardware capabilities;

5, the game may not function properly;

6, application cannot normally use.

Third, the part may be involved

The motherboard, CPU, memory, power supplies, disk, keyboard, patch, the Board

IV. judgments points/order

1. preparation before maintenance

1) clean free hard disk;

2) anti-virus software;

3) as a new driver, several versions of the BIOS;

4) disk connection cables, etc.

2, environmental checks

1 check the outputted by commercial power supply and connection):

A. check whether the normal power supply, connection is led by the sad; is there a grounding;

B. the connector between devices is wrong or missed.

2) surrounding the appearance inspection and:

A. check with other peripherals hosts connections work properly;

B. drive work when abnormal sound, the CPU fan speed is too slow or unstable;

C. observation of in-the-box is too much dust, resulting in the poor contact between connectors. First dust available rubber etc., wipe the Goldfinger, removal of oxide layers or dust. And then plug it in again;

D. observation system have the unusual smell, components of temperature is too high or too fast.

3) displays and sets a check:

A. detailed records an error, the judgment may cause malfunction of the site;

B. Note CMOS for hard drives, system time, CPU temperature settings, note in the post shows the hardware information and machine configurations are matched;

C. carefully read the guidelines on the use of the software, attention to environmental requirements for software operation.

4 full communication with the user):

A. aware of the use of the user;

B. failure before the phenomenon;

C. What do appear at present to xx.

According to the above information, an initial judgment by possible failure reasons.

3. fault points

1) checks whether a result of user error xx for cause

A. machine panic, blue screen or without restart, it is first necessary to consider to make the user's compliance with xx xx for specifications and requirements, to carefully observe the user's inquiry, xx for method is consistent with common sense and by engineers with the right methods for application users, xx machines to see if a repair by the user. If it does not appear, you may think that is a user incorrectly made xx, explain to the user by engineers and demonstrates the correct method for xx.

B. If, after the xx for fault persists, use System File Checker checks the user's machine if the system has the missing DLL files, and attempt to recover.

C. observe the user's machine in panic, blue screen or when there is no reason to restart without law, and to identify possible causes of failure caused by machine (if the machine is running a program or a machine turned on at one time, panic).

D. by with another identical hardware and without fault of the machine, check the machine's file size are the same or similar, the main program versions are the same.

2) check whether due to a virus, or failure caused by antivirus programs

A. check the user's machine is infected with a virus, the use of anti-virus software antivirus;

B. check that the user has installed two or more anti-virus software, we recommend that users use one and uninstall other antivirus software;

C. check to see if the Trojan program, use the latest version of anti-virus program can detect a Trojan. You can install a patch to remedy the security vulnerabilities in programs, or Firewall installation.

3) check whether due xx for system problems caused by the fault

A. check the hard disk has adequate free space, and check whether too many temporary files. Defragment the hard disk space, delete unneeded files;

B. for system files are corrupted or lost, you can use the System File Checker to check and repair;

C. check xx for system is installed on the appropriate system patch (for Winnt may observe servicepack at startup, it is recommended to use a version of SP6; Win2k and Winxp can view in system properties, Win2k Winxp SP3, recommended, recommended the use of SP1. ）；

D. check the DirectX driver properly, upgrade the version of DirectX;

E. check the correct installation of the device driver and the driver version is appropriate. Check the driver installation order is correct (for example: first install the motherboard driver).

4) check the software compatibility failure caused by the conflict,

A. check the user application software environment is made with existing xx systems (NT/98/2K/XP) compatible, you can view the software manual or to the software page to find the relevant information, and view the Web page is there for this software upgrades or patches can be installed.

B. free Task Manager observation failed machine background if there is no normal program running, and attempt to close the program keep only the most basic background programs.

C. pay attention to see whether there is a fault within the shared DLL files, you can change the order of installation or installation directory to resolve the issue.

5) check the hardware settings are not correct

A. first, check the CMOS settings are correct, you can restore the default values;

B. check the Device Manager, hardware is functioning interruption whether there is a conflict, if conflicts,adjust the system resources (for some hardware, to read the instruction manual, follow the instructions for the correct settings for the hardware);

C. in the Device Manager to remove the hardware driver, reinstall drivers (preferably installed the correct version of the driver), view the hardware driver is back to normal;

D. run hardware detection program, such as AMI and other testing hardware is faulty;

E. software minimum system, new updates hardware drivers, observation of failure could disappear.

6) checks for compatibility issues

A. encounter compatibility problems, you should check the hardware specifications and standards (such as using multiple memory check memory is the same manufacturer, same size, same capacity, memory, particles of the same batch), whether or not to allow.

B. read the instruction or to find relevant information on a Web page, check the user's hardware normal use of the software requirements, software environment meets the requirements, whether between hardware and support each other.

C. in the Device Manager checks the user's system resources if there is a conflict, if conflicts, manually adjust the system sources.

D. in the Device Manager to check the user's machine hardware driver is correctly installed, update the appropriate version of the device driver (like some video cards with WIN2000 or WINXP with a public version of the driver, will cause some large 3D game cannot run);

E. checks and maintenance to BOM, unless the Association's hardware, check whether the system is to function properly, such as being able to work properly, we recommend that users replace to add hardware or find hardware-related information for resolution.

7) check whether due to network failure

A. touch the machine on the network, the panic and run slow, blue screen, and so fails, you should first turn off the network, and network environment, whether failure to observe, such as faultdisappears disappeared, as network problems caused the failure.

B. There are network problems caused by the fault, their judgment and resolution steps refer to the network segment.

8) check if poor performance due to hardware or damage caused by

A. using the appropriate hardware detection program, check the hardware is faulty, and if so, use alternate method to exclude appropriate hardware;

B. use the Replace method detection program is unable to determine the hardware failure.

Report: IE delete temporary files available in the following ways:

1, open the IE browser and tools-internet options, delete temporary files, empty the history. (For IE cannot open the item in the settings below "InternetExplorer" every boot, or temporary Internet files folder using disk space increase;

2. in the start-settings-taskbar and start menu-choose to clear the start menu programs;

3, in the historical c:\windows\history directory deletion;

4. delete all files in the c:\windowsTemporaryInternetFiles;

5. use of the network and other third-party software to clear.
