一、Blue screen faults often occur under Windows. Such faults manifest themselves in various ways，Sometimes it appears when Windows starts，Sometimes it occurs when running some software under Windows，Such failures are generally caused by improper user operations that damage the Windows system，This type of phenomenon is specifically manifested in the inability to enter the system normally when booting in safe mode，A blue screen failure occurred。Sometimes too many fragments can cause this kind of failure，Once the author solved the problem after defragmenting，If this possibility is excluded, there are several reasons that may cause this fault。

1、Memory reason。This fault is common due to memory reasons，Such failures are generally caused by poor chip quality，But sometimes we can solve this problem by modifying the delay time CAS in the CMOS settings (changing it from 3 to 2)，If it doesn’t work, you can only replace the memory module。

2、Mainboard reason。The probability of this failure due to the motherboard is slightly lower than that of the memory，Generally after this kind of failure occurs due to motherboard reasons，The computer generally does not crash after a blue screen，And failures occur frequently，The only way to do this is to replace the motherboard。

3、CPU reason，Such failures due to CPU reasons are relatively rare，Generally common on cyrix CPUs，For this we can reduce the CPU frequency，See if it can be solved，If not possible，The only way is to replace it。

二、A general protection error occurs when the computer starts in Windows in normal mode. The reasons for such failures generally include the following:

1、Memory module reason。If it is due to memory，We can change the CAS delay time to see if the problem can be solved，If the memory module is working at a non-66MHz FSB，For example 75MHz、83MHz、Frequency of 100MHz or above，We can try it by reducing the FSB or memory frequency，If not possible，Only if it is replaced。

2、Bad sectors on disk。If it is caused by bad sectors on the disk，We can boot the system in safe mode，Use ScanDisk to fix hard disk errors，See if the problem can be solved。After bad sectors appear on the hard disk，m88 slot machine casinoIf not repaired in time，It may lead to a gradual increase in bad sectors or complete damage to the hard disk，Therefore，We should fix it as soon as possible。

3、windows system damaged。This can only be solved by reinstalling the system。

4、The anti-virus function is turned on in the CMOS settings。This type of fault usually occurs during system installation，There will generally be no problem if you enable this function after the system is installed。

1、Frequent computer crashes caused by viruses. This failure is relatively common due to such reasons，When the computer is infected with a virus，Mainly manifested in the following aspects: ① Extended system startup time；②Some unnecessary programs automatically start when the system starts；③Crash for no reason④Some garbled characters appear on the screen。Its expressions are endless，Due to space reasons, this is the introduction，What needs to be mentioned here is，If some system files are damaged due to viruses，Resulting in unstable system operation，We can use System File Checker to repair system files in safe mode。

2、This type of failure is caused by poor thermal stability of some components (specifically manifested in the CPU、Power supply、Memory module、Motherboard) to this，We can let the computer run for a while，Wait until it crashes，Touch the above components with your hands，If the temperature is too high, there may be a problem with the component，We can use substitution method to diagnose。It is worth noting that it is best to apply some thermal grease when installing the CPU fan，But I can hardly see it on some assembled computers，Practical proof，Silicone grease can lower the temperature by about 5-10 degrees，Especially on PIII computers，If no thermal grease is applied，The computer simply doesn’t work properly，The author has encountered such a phenomenon once。The main configuration of this machine is as follows: Panying 815EP motherboard、PⅢ733CPU、133 FSB 128M memory module，When the machine is assembled，Frequent crashes，Even the Windows system cannot be installed normally，But after replacing the CPU of Celeron 533，Troubleshooting，Suspect there is a problem with the motherboard or CPU，But replace the motherboard with the same model、This fault cannot be solved even after using the CPU。Later, it was found that its temperature was too high，Apply some thermal grease on the CPU，The fault is completely solved。Practice has proven that thermal grease must be m88 online bettingapplied to CPUs above Celeron 533，Otherwise it is very likely to cause a crash。

3、It is common for computers to frequently crash due to poor contact between components，Especially on computers that have been purchased for a while。Because most of the components are in contact with the motherboard by golden fingers，After a period of time, oxidation will appear on the gold finger area，After removing each card, you will find that the gold finger area has turned yellow，At this time，We can use an eraser to wipe the yellowed areas back and forth to clean them。

4、The computer frequently crashes due to incompatibility between hardware. This phenomenon is common when the graphics card is incompatible with other components or the memory module is incompatible with the motherboard，For example, SIS graphics card，Of course, other devices may also be incompatible，For this purpose, you can use other unnecessary equipment such as Modem、Judge after removing the sound card and other equipment。

5、Software conflicts or damage causing crashes，usually happens at the same point，This can be solved by uninstalling the software。

four、The computer appears when Windows starts the system*.Vxd or other files not found，Press any key to continue. This type of failure is usually caused by the user not deleting it completely when uninstalling the software or incorrectly installing the driver when installing the hardware.，To this，We can enter the registry management program，Use its search function，Will prompt for files not found，Resolved by deleting it from the registry。

五、When Windows boots to the login dialog in normal mode，There is no icon on the desktop after clicking "Cancel" or "OK"，No operation can be performed。This type of failure is generally due to improper user operation，causing system damage。The solution is as follows: first we boot the system in safe mode，Enter control panel，Enter "Password" option，Set User Profile to "This desktop user uses the same desktop and preferences"，Enter "Network"，Delete everything except "Dial-up Network Adapter"，Make the login method Windows login，Restart computer，can be solved。

Six、When the computer restarts when shutting down under Windows, I saw in a recent article in Computer News that the solution is to defragment the hard disk or reinstall Windows，In fact it’s not the case，This type of failure is usually caused by the user inadvertently or using some software to set up the system，Using the quick shutdown function of Windows system，thus causing this fault，The solution is as follows: click "Start" - "Run" - "msconfig"，Select Advanced in the System Configuration Utility panel，Select "m88 slot machine casinoDisable Quick Shutdown"，Restarting the computer will solve the problem。

seven、Chinese characters are lost in Windows and other software is installed after Windows is installed on the computer，When defragmenting the hard drive，System prompt: "Hard disk fragment contains errors"。After repairing with SCANDISK，The fragmented truth cannot be used，When entering Windows attachments，I found that the Chinese characters were missing。Checked that there is no virus，Check SCANDIDSK again.LOG file，Prompt: "Folder C: WINDOWS has been damaged..."。According to the above fault phenomenon，Garbled Chinese characters in Chinese Windows，Mostly caused by the loss of Chinese character display content in the registry。At this time，Open Registry Editor (WINDOWSREGEDIT.EXE)，Open the two lines of keywords "Associated Default Fonts" and "Associated Char Set"，If any，Open these two lines of keywords respectively to see the contents。When there is only the "Default" line and no other content，Indicates that the relevant Chinese character display cannot be defined，The reason why Chinese characters are garbled。

Can be repaired manually.

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

(2)In the "Run" dialog box，Type regedit，Click OK，Open Registry Editor。

(3) Expand "My Computer HKEY—LWCAL—MACHINE Systemcurrent Control SetControl Fontassoc" and check whether there is an "Aossiated Char Set folder icon" under it，In the right column of the window，The following content will be added: ANSI (00) "Yes" GB2312 (86) "Yes" WEM (FF) "Yes" SYMBOL (02) "on" The method to add is: in the edit new menu，Click "String Value"，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 can be deduced in the same way。

(4)Follow the above method，Click the Associated Default Fonts file icon，The following content will be added to the right column of its window: 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 "宋体"

(5) When there are no keywords in the "Associated Char Set" and "Associated Default Fonts" lines，Fontassoc folder，Under Edit New Menu，Click "Primary Key"，In the text box that appears，Type the above two lines of keywords respectively，Then follow step (4) to add the listed content。

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

eight、The printer cannot print under Windows. Make sure the printer is intact，First the user enters DOS state (pure DOS)，Enter dir> at the command m88 best betting websiteprompt;prn or press the "Print screen sysrq" key on the keyboard，See if the printer can print，If it doesn’t work, you can usually judge that there is a problem with the motherboard’s printing port or printing cable，But according to the author’s experience, it may be related to the print port mode in the cmos settings (usually Ecp、Epp、Spp several) settings related，Users can change the test accordingly，There is another special situation，ucdos when the printing port is damaged、Can print under Windows，But it cannot be printed according to the above detection method or under the Li De business card system，This can only be solved by adding a multi-function card (after adding a multi-function card, you must block the IDE on the motherboard、com、Print port)。If it can be printed under Dos，You can solve it by following the following methods: ①Under Windows，Enter the system properties of the control panel，Check whether the printing port LPT1 exists，If not, enter the control panel--Add new hardware，Let it search for new hardware，Just add the found printing port。②Whether the driver has been installed correctly，Reinstall printer driver。③Whether there is remaining space on the disk where system files are installed，Generally, there will be a prompt of insufficient memory if there is insufficient space，Just uninstall some software。④The computer may be infected with a virus。

Nine、When running an application under Windows, it prompts that there is insufficient memory. Generally, there may be several reasons for the insufficient memory prompt: ① Insufficient remaining disk space，Just delete some files accordingly。②Multiple applications are running at the same time。③The computer is infected with a virus。

十、The characters printed by the printer under Windows are all garbled. This type of failure is usually caused by the printer driver not being installed correctly or the parallel port mode settings not matching，The solution to the first situation is relatively simple，If it is the second situation, you can enter the Cmos settings and change the parallel port mode and test one by one (usually with Ecp、Epp、Spp three kinds)。
