Seven, Chinese characters are lost in Windows;

After installing Windows in the computer and installing other software, when defragmenting the hard disk, the system prompts: "The hard disk fragment contains errors." After repairing with SCANDISK, the fragmentation truth could not be used. When I entered the Windows attachment, I found that the Chinese characters were gone. After checking that there is no virus, check the SCANDIDSK.LOG file, prompting: "Folder C: WINDOWS has been corrupted.........".

According to the above fault phenomenon, Chinese characters are garbled in Chinese characters, mostly due to the loss of content displayed in the registry about Chinese characters. At this point, open the registry editor (WINDOWSREGEDIT.EXE), and then open the "Associated Default Fonts" and "Associated Char Set" two lines of keywords, if any, then open these two lines of keywords to see which content. When there is only one "default" line and no other content, it means that the relevant Chinese character display cannot be defined, which is the reason for the Chinese characters garbled. ;

Can be repaired by hand. ;

(1) Click "Start" and select "Run". ;

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

(3) Expand "My Computer HKEY-LWCAL-MACHINESystemcurrent Control SetControl Fontassoc" to see if there is an "Aossiated Char Set folder icon underneath, in the right column of the window, the following will be added:; Br>

ANSI(00)“Yes”;
GB2312(86)“Yes”;
WEM(FF)“Yes”;
SYMBOL(02)“on”;

Add the method: In the Edit New menu, click "String Value", then in the text box that appears in the right column, type ANSI (00), then double-click the text box, in the dialog box that appears, type Yes, click "OK", the rest of the added content and so on.;

(4) According to the above method, click the Associated Default Fonts file icon, the right column of the window will add the following:

Assoc System Font "Simsun, ttf";
Font Package Decorative "宋体";
Font Package Dont Care "宋体";
Font Package Modern "宋体";
Font Package Roman "宋体";
Font Package Script "宋体";
Font Package Swiess "Song";

(5) When there are no two words "Associated Char Set" and "Associated Default Fonts", then the Fontassoc folder, under the Edit New menu, click "Primary Key" Then, in the text box that appears, type the above two lines of keywords, then press step (4) to increase the listed content.;

(6) Shut down the system, restart the computer.; >

Eight, the printer can not print under Windows;

In the case of confirming the printer is intact, the user first enters the DOS state (pure DOS), enter dir>prn at the command prompt or press on the keyboard "Print screen sysrq" button, to see if the printer can print, if not, you can judge the motherboard's print port or print cable problem, but according to the author's experience may be related to the print port mode in the cmos settings (usually Ecp, Epp, Spp several) related settings, the user can change the test accordingly, there is a special case, when the print port is damaged, ucdos, Windows can print, but can not print according to the above detection method or Reed card system Only add this versatile card can settle (plus multifunction card after going to the shield on the motherboard IDE, com, LPT). If Dos can print, you can solve it as follows:

1 Under Windows, enter the system properties of the control panel, see if the print port LPT1 exists, if there is no access to the control panel - add new Hardware, let it search for new hardware, and then add the found print port to it. ;

2 If the driver has been installed correctly, reinstall the printer driver. ;

3When the disk of the installation system file has free space, there is a shortage of memory in general, so just remove some software. ;

4 The computer may be infected with a virus.
Nine, when running the application under Windows, the memory is insufficient;

There are several reasons why there may be insufficient memory:

1 The remaining disk space is insufficient, as long as Delete some files accordingly. ;

2 Run multiple applications at the same time. 3 The computer is infected with a virus.

Ten, the words printed by the printer under Windows are garbled;

This type of fault is generally caused by the printer driver not being installed correctly or the parallel port mode setting is not relevant, for the first type The situation solution is relatively simple. If the second case can enter the Cmos setting, change the parallel port mode and test it one by one (generally Ecp, Epp, Spp).

XI. Illegal operation prompts when running the application under Windows;

There are many reasons for this type of failure, and there are several possibilities:

1 System file was changed or damaged. If this happens, then some programs that come with the system will be opened, and an illegal operation prompt will appear (for example, open the control panel). ;

2 driver is not installed correctly, such failure is generally on the graphics card driver, if this is triggered, open some game programs will generate an illegal operation prompt, I have encountered After a special phenomenon caused by this, sometimes there is a prompt for illegal operation when opening certain web pages.

3 The quality of the memory is not good (sometimes to increase the memory delay time to the system default 3 to 2 can solve such failure).

4 Sometimes if the sound card driver is not installed during the running of the program, such a failure will occur. For example, if the sound card driver is not installed, an illegal operation error will occur during the operation.

5 software is not compatible, for example, IE5.5 is installed on the second version of win98 system. When IE opens multiple windows at the same time, it sometimes generates an illegal operation prompt. ;

12. After the successful dialing, the webpage cannot be opened;

After the fault occurs, there are the following phenomena:;

1. The prompt cannot open the search page. Such failures are generally caused by problems with the network configuration. Go to the "Control Panel" - "Network", delete all the items except the dial-up adapter, restart the computer and then add the "TCP/IP protocol" of Microsoft to restart the computer. ;

2. Some sites that can enter can't go in and find the site for a long time. Some MODEMs can cause such faults if the user does not specify a local IP address for them. You can enter the MODEM setting item and assign a local IP address to it. For example, the IP address of Hunan is 202.103.96.68. Another possibility may be that the user has optimized the software with fast cats and whip. For this, you can reinstall the network option according to the method described above or restore the registry to see if the problem can be solved. If not, the author's experience is only re The system can be solved by installing the system. ;

3. In the IE browser of Windows, in order to restrict access to certain internet sites, you can enable "gradation review" in the "Content" page of the "Internet" setting of "Control Panel". Users can limit the different content levels, but when we browse the page with activex, the password dialog box will always ask us to enter the password. If the password is incorrect, we will not be able to see the page. After the password is forgotten, the user cannot browse normally. The solution is to delete the password by modifying the registry. Here's how:

Open the Registry Editor and find HKEY_LOCAL_MACHINESoftwaremicrosoftwindowscurrent versionpolicies atings. Stored under this sub-health is the encrypted password. The rating subkey is deleted and the IE password is removed.

Thirteen, 3DMAX can not be started after normal installation;

This type of failure is generally caused by the incomplete installation of the user's windows system files, windows will generally be less installed under normal installation conditions. The following files: vdd.vxd, vcomm.vxd, vmouse.vxd, vflatd.vxd, vdmad.vxd, configmg.vxd, ntkern.vxd, we just need to add it, as follows: Click Start - Program --Attachment--System Tools--System Information, then click "Tools"--System File Checker, select to extract files from the installation floppy disk, input the above mentioned files in the blank column, and solve the problem after the extraction is completed. . ;

XIV, the computer automatically restarts;

Such failures are manifested in the following aspects: such failures occur at system startup or after the application has been running for a while. The cause of this fault is generally caused by poor thermal stability of the memory module or unstable power supply operation. Another possibility is that the CPU temperature is too high. There is also a special case, sometimes due to conflicts between the driver or some software, causing the windows system to generate the fault at boot time. ;
