Troubleshooting of common Windows operating system faults (1)

When using a Windows operating system, there will always be one or another failures. How can we solve these faults? It is a difficult problem. This article lists some common troubleshooting methods and hope to help you.

I. Blue Screen failures often occur in Windows

This type of fault may occur in a variety of ways, sometimes when Windows is started, and sometimes when some software is running in Windows. This type of fault is generally caused by improper user operations that cause Windows system damage, this type of phenomenon is manifested in a blue screen fault that occurs when the system fails to normally enter the system during security mode guidance. Sometimes too many fragments may cause such a fault.

The fault is solved after the fragments are sorted out. If this fault is ruled out, the fault may be caused by the following reasons.

1. Memory reason. Memory causes this fault, which is generally caused by poor chip quality, but sometimes we can solve this problem by modifying the delay time CAS (from 3 to 2) in the CMOS settings. If not, only the memory is replaced.

2. Main Board reasons. The probability of a fault caused by the motherboard is slightly lower than that caused by the memory. Generally, after the motherboard causes such a fault, the computer will not crash after the blue screen, and the fault occurs frequently. Only one way to change the motherboard is to do this.

3. For CPU reasons, such faults are rare due to CPU reasons, which are generally common in the CPU of cyrix. In this case, we can reduce the CPU frequency to see if it can be solved. If not, only change the path.

2. General Protection errors occur when the computer is started in normal mode on Windows.

The causes of such faults are generally as follows:

1. Memory Stick reason. For memory reasons, we can change the CAS delay time to see if the problem can be solved. If the memory stick is working at a non-66 MHz external frequency, for example, if the frequency is 75 MHz, 83 MHz, MHz or above, we can try it by reducing the external frequency or memory frequency. If not, we only need to change it.

2. Bad Sectors on the disk. If the disk has a bad track, we can use the safe mode to guide the system, and then use the disk scanner to fix the hard disk error to see if the problem can be solved. If a bad track occurs on the hard disk, it may increase or damage the hard disk. Therefore, we should fix it as soon as possible.

3. Windows is damaged. This can be solved only by reinstalling the system.

4. Enable anti-virus in the CMOS settings. This type of fault usually occurs during system installation. Enabling this function after the system is installed will not cause any problems.

Iii. Random computer crashes

Crash failures are common, but they are difficult to maintain because of their wide scope. Now I will explain them in detail.

1. Frequent computer crashes due to viruses

This fault is often caused by such reasons. When a computer is infected with a virus, it is mainly manifested in the following aspects:

① Extended system start time;

② Some unnecessary programs are automatically started when the system starts;

③ Crash without reason

④ Some garbled characters appear on the screen.

Its forms of expression emerge one after another. Due to the reason of the length, we need to mention that if the virus damages some system files, the system may be unstable, in security mode, we can use the System File Checker to fix system files.

2. This type of fault is caused by poor thermal stability of some components (including CPU, power supply, memory stick, and motherboard)

In this regard, we can let the computer run for a period of time, after it crashes, and then touch the above parts by hand, if the temperature is too high, it indicates that this Part may have problems, we can use replacement method for diagnosis. It is worth noting that it is best to apply some heat-cooled Silicon grease when installing the CPU fan, but it is difficult for me to see it on some Assembled computers, silicon grease can reduce the temperature by about 5-10 degrees, especially on p iii computers. If no heat dissipation silicon grease is applied, the computer cannot work normally. I have encountered such a phenomenon once. The main configuration of the machine is as follows: 815EP motherboard, P Ⅲ 733CPU, 133 external frequency M memory, when the machine is assembled, frequent crashes, even Windows system cannot be installed normally, however, after replacing the CPU of SAI Yang 533, the fault will be rectified and the problem may occur on the motherboard or CPU. However, after replacing the motherboard or CPU of the same model, the fault cannot be solved. Later, due to the discovery that the temperature was too high, some heat dissipation silicon grease was applied to the CPU, and the fault was completely solved. Practice has proved that heat dissipation silicon grease must be applied to the CPU of more than 533 of the competition, otherwise it is very likely to cause a crash.

3. Frequent computer crashes due to poor contact with various components

This type of phenomenon is common, especially on a computer that has been purchased for a period of time. Since most of the parts are in contact with the motherboard by using the golden finger, oxidation may occur in the parts of the Golden finger after a period of time. After removing the cards, the golden finger is yellow, we can use an eraser to clean the yellowing area.

4. Frequent computer crashes due to hardware incompatibility

This type of phenomenon is common when the video card is incompatible with other components or the memory stick is incompatible with the motherboard. For example, the SIS video card may also be incompatible with other devices, in this case, you can remove unnecessary devices, such as Modem and sound card, and then judge them.

5. Software conflicts or damages cause crashes

This kind of fault usually happens at the same point, which can be solved by removing the software.

4. When the computer starts Windows, *. Vxd or other files are not found. Press any key to continue the fault.

This type of fault is generally caused by the installation of the driver when the software is uninstalled or the installation of hardware is incorrect. In this case, we can go to the Registry management program and use its search function, an unfound file will be displayed, which can be deleted from the registry.

5. When guiding to the logon dialog box in normal Windows mode, click "cancel" or "OK" without any icons on the desktop.

Such faults are generally caused by improper user operations and system damage. The solution is as follows: first, guide the system in safe mode, enter the control panel, and enter the "password" option, set "user configuration file" to "this desktop user uses the same desktop and Preferences", go to "network", and delete items other than "dial-up network adapter, use Windows to log on and restart the computer.

6. restart the computer when it is disabled in Windows.

In a recent article on the PC newspaper, I found that the solution is to organize the hard disk or reinstall Windows, this type of fault is generally caused by the quick shutdown function of the Windows system when the user inadvertently or uses some software that sets the system. The solution is as follows: click "start"-"run"-"msconfig", select advanced in the "System Configuration Utility" panel, and select "Disable quick shutdown, restart the computer to solve the problem.

7. Chinese characters lost in Windows

After Windows is installed on the computer, other software is installed. When the hard disk fragments are sorted out, the system prompts "the hard disk fragments contain errors ". After SCANDISK is used for restoration, the fragment truth cannot be used. When I enter the Windows attachment, I find that the Chinese characters are missing. After checking that there is no virus, check the SCANDIDSK. LOG File and prompt "the folder C: \ Windows has been damaged .........".

According to the above fault, Chinese characters garbled in Chinese Windows are mostly caused by the loss of Chinese character display content in the registry. Open the Registry Editor (Windows \ REGEDIT.. If there is only one "default" line and no other content, it indicates that the relevant Chinese character display cannot be defined, which is the reason why Chinese characters are garbled.

You can fix the issue manually.

(1) Click Start and select Run ".

(2) In the "run" dialog box, type regedit and click "OK" to open the Registry Editor.

(3) expand my computer \ HKEY-LWCAL-MACHINE \ System \ current Control Set \ Control Fontassoc to see if there is a "Aossiated Char Set folder icon under, in the right bar of the window, the following content will be added:

ANSI (00) "Yes"

GB2312 (86) "Yes"

WEM (FF) "Yes"

SYMBOL (02) "on"

Add method: in the edit \ new menu, click "string value", type ANSI (00) in the text box that appears in the right column, and then double-click the text box, in the displayed dialog box, type Yes and click "OK". The other added content is pushed accordingly.

(4) follow these steps and click the Associated Default Fonts file icon. The following content is added to the right column of the window:

Assoc System Font "Simsun, ttf"

Font Package Decorative ""

Font Package Dont Care ""

Font Package Modern ""

Font Package Roman ""

Font Package Script ""

Font Package Swiess ""

(5) If there are no "Associated Char Set" and "Associated Default Fonts" keywords, click "primary key" under the "Edit \" menu in the Fontassoc folder ", then, in the text box that appears, type the above two line keywords, and add the listed content according to step (4.

(6) Shut down the system and restart the computer.
