Issue 1 8692 DOI 1025236AJCIS2024070113 Published by Francis Academic Press UK 89 problems such as unstable power supply thus affecting the normal operation of the equipment 9 Although natural disasters cannot be completely avoided their impact can be reduced by taking some preventive measures such as using lightning protection equipment and regularly checking power supply lines 43 ManMade Damage Human damage is another important cause of computer hardware equipment failure User improper operations accidents or malicious attacks can cause hardware damage For example the accidental dropping of a keyboard mouse or other external device or the destruction of a system by malware It is worth noting that human damage can be avoided and users should take care to use the computer properly and avoid placing fragile external devices on unstable surfaces while regularly updating the system and antivirus software to guard against malicious attacks 44 Software Conflict Software conflict is also one of the causes of computer hardware equipment failure Some software may be incompatible with the hardware device causing the device to fail to run properly For example some drivers do not match the operating system version which may cause the hardware device to not work properly However software conflicts can be resolved by choosing a more compatible software version or updating drivers Before installing new software or updating drivers it is recommended to back up important data and review relevant compatibility information 45 Other Reasons In addition to the above reasons there are other factors that can cause computer hardware equipment to fail For example the compatibility of hardware devices and the impact of the use environment These factors may alone or in combination with other causes lead to hardware device failure For faults caused by other causes analyze the faults on a casebycase basis For example for compatibility issues you can select an operating system or software version that is compatible with the hardware device For the impact of the use environment the use environment can be improved to reduce the damage to the hardware equipment 10 5 Computer Hardware Equipment Maintenance Methods 51 Power Failure Maintenance Methods A power failure can cause your computer to fail to boot or shut down suddenly For a power failure first check that the power plug and socket are securely connected to ensure that the power cord is not damaged If there is no problem with the power cord try replacing the power supply or power cord If the problem still cannot be resolved it may be necessary to further inspect the power outlet or power adapter for damage 11 Specific operation method 1 Check whether the power plug and socket are securely connected 2 Check whether the power cable is damaged or loose 3 Replace the power supply or power cable If the problem persists check the power outlet or adapter for damage 52 Motherboard Fault Maintenance Methods Motherboard failure can cause the computer to fail to boot the system to crash or peripherals to not work properly If the main board is faulty first check whether the circuit on the main board is short circuited or whether the interface is damaged If the circuit is not faulty you can try to replace the chip or interface on the motherboard If the problem still cannot be resolved it may be necessary to further inspect other components on the motherboard for damage Specific operation method Academic Journal of Computing Information Science ISSN 26165775 Vol 7 Issue 1

the main board 53 Memory Fault Maintenance Method Memory failures can cause your computer to run slowly programs to crash or systems to become unstable If the memory module is faulty check whether the memory module is loose or in poor contact If the memory module is normal replace the memory module or adjust the memory configuration If the problem still cannot be resolved you may need to further check the memory for damage or compatibility issues Specific operation method 1 Check whether the memory module is loose or in poor contact 2 Replace the memory module or adjust the memory configuration 54 Hard Disk Fault Repair Method A disk failure may cause data loss system failure or slow readwrite speeds If a hard disk is faulty check whether the hard disk is physically damaged or has logical errors If there is no problem with the hard drive you can try to reinstall the operating system or use a professional data recovery tool to recover the data If the problem still cannot be resolved it may be necessary to further check the hard drive for interface problems or other hardware failures 12 Specific operation method 1 Check whether the hard disk is physically damaged or has logical errors 2 Try reinstalling the operating system or using a professional data recovery tool to recover the data 55 Other Troubleshooting Methods In addition to the above common failures computer hardware devices may also encounter various other problems such as display failure keyboardmouse failure network adapter failure to connect For these faults you need to check whether the related hardware devices are securely connected or working properly If there is no problem with the hardware device you can try to update the driver or reinstall the related software to resolve the problem If the problem still cannot be resolved it may be necessary to further inspect the hardware device for damage or other problems 6 Computer Hardware Equipment Maintenance and Maintenance Recommendations Computer hardware equipment is an expensive investment and if regular maintenance is not performed the equipment may be prematurely damaged due to frequent use resulting in failure to function properly Through regular maintenance and maintenance the dust inside the computer can be cleaned up and the hardware equipment can be kept in good working condition thus extending the service life of the equipment 61 Remove Dust and Dirt Regularly Computer hardware equipment longterm use easy to accumulate dust and dirt These dust and dirt will not only affect the appearance of the equipment but also may affect the normal operation of the equipment The accumulation of dust may reduce the heat dissipation efficiency and cause the operating temperature of the device to be too high which reduces the service life of the device Therefore it is very important to remove dust and dirt regularly For example a user found that his computer running slower while the buzz after inspection found that the cooling fan accumulated a lot of dust after cleaning the computer running speed significantly increased the buzz also disappeared This case illustrates the importance of cleaning dust regularly not only to improve the operating efficiency of equipment but also to solve some potential failure problems Academic Journal of Computing Information Science ISSN 26165775 Vol 7 Issue 1 8692 DOI 1025236AJCIS2024070113 Published by Francis Academic Press UK 91 62 Check Whether the Hardware Connection Is Secure An insecure hardware connection may cause the device to fail to work properly or to fail frequently Therefore it is necessary to regularly check whether the hardware connection is firm For example a classmates computer suddenly cannot start normally after inspection found that the memory is loose caused After reinstalling the memory the computer can start up normally This case illustrates the importance of checking hardware connections to find and resolve some common faults in time 63 Use Appropriate Cooling Equipment and Cooling Paste Computer hardware devices generate a lot of heat during operation If the heat is not properly controlled it may cause the equipment to overheat or even burn Therefore it is very important to use the appropriate heat dissipation equipment and heat dissipation paste For example a student found that his computer often crashed when running a large game After inspection it was found that the CPU was overheating After replacing the cooling fan and applying the cooling paste the problem was solved This case illustrates the importance of using the right cooling equipment and cooling paste to ensure the normal operation of the equipment 64 Avoid Using Computers in Harsh Environments Computer hardware devices have high requirements on the environment For example if a computer is used in a humid hightemperature and dusty environment device faults may occur Therefore it is very important to avoid using computers in harsh environments For example a student often uses his computer in the bathroom Due to excessive humidity the internal corrosion of the keyboard eventually causes the keyboard keys to fail 13 This case illustrates the importance of avoiding the use of computers in harsh environments to protect equipment from damage 65 Back up Important Data and Files Regularly Data and files in computer hardware devices are very important and can cause serious losses once lost or damaged Therefore regular backup of important data and files is very necessary For example a user did not back up important company files in time resulting in file loss after a computer virus attack Later although some files were recovered by technical means certain losses were still caused This case illustrates the importance of regularly backing up data to avoid data loss due to unexpected circumstances 66 Follow Proper Shutdown and Restart Procedures Proper shutdown and restart procedures can protect computer hardware devices from damage Incorrect shutdown and restart methods may result in device damage or data loss For example a user found that the computer could not start normally after a forced shutdown and it was found that the hard disk was damaged A forced shutdown may cause the disk head to fail to return to normal position resulting in disk damage This case illustrates the importance of following proper shutdown and restart procedures to protect the device from damage 14 7 Conclusion Common faults of computer hardware equipment include CPU failure memory failure hard disk failure motherboard failure and power failure These failures may affect the normal operation of the computer and even cause system crashes or data loss There are different maintenance methods for different types of hardware faults For example a CPU failure may manifest as a computer failing to turn on or frequently crashing mainly due to excessive CPU temperature or lock failure In this case check the fan and heat sink and remove and reinstall the CPU If the memory is faulty blue screen of death BSOD or startup failure may occur To rectify the fault replace the memory module or clear the memory module slot A hard disk fault may cause a computer crash or failure to read data You can install a hard disk test tool to diagnose the fault and replace the hard disk In a word the study of common faults and maintenance methods of computer hardware equipment is of great significance to ensure the normal operation of computers By understanding the common fault types and maintenance methods the computer hardware equipment can be better maintained and managed and the operation Academic Journal of Computing Information Science ISSN 26165775 Vol 7 Issue 1 8692 DOI 1025236AJCIS2024070113
