1. Recently, too much pressure leads to sleep quality is not very good, do some strange dreams, often are thinking every day, night dreams, don't worry, dreams are reverse, try to release pressure, drink a cup of hot milk before going to bed can improve sleep quality, hope to help you, hope to adopt, thank you
2. Dreams have nothing to do with good or bad luck. They are often caused by people's memory ring the day, that is, they have thoughts every day and dreams at night
ha ha, dreams are formed by the brain unconsciously linking the information in the brain in disorder. Some of the information that you have long forgotten will be called at the edge of memory. It's amazing
but in fact, most dreams can't foresee reality. If dreams can foresee reality, and this kind of foreseeing can be interpreted, and this kind of capable person does exist, I can say that 99.99999% of the people with this kind of capable person can not meet once in their lifetime
many people have this kind of distress: after falling asleep, they often have nightmares or even wake up. As a result of sleep, dizziness the next day, affect the work and study. Some also worry that nightmares will bring bad luck to themselves, causing psychological fear and uneasiness< In fact, dreaming is a normal psychological phenomenon in the process of sleep. Under normal circumstances, human brain nerve cells are in a state of inhibition ring sleep. Sometimes the inhibition process is relatively complete, sometimes not complete. If not completely inhibited, there are a few areas of the cerebral cortex in the nerve cells excited, people will have dreams. Because the activity of a small number of cells lost the control and regulation of the whole cerebral cortex when they were awake, some segments in memory became active without restriction, which may show strange dreams different from normal psychological activities. At this time, if the nerve cells related to language and movement are also in an excited state, they will not only have dreams, but also talk or walk in dreams
so how can we rece nightmares
to rece adverse stimulation. At ordinary times, we should watch more healthy and pleasant videos or novels, and less or try not to watch movies or novels that are easy to form nightmares, so as to avoid bad stimulation stored in memory. It's best not to overuse the brain before sleep, so as not to cause dreams e to excessive excitation of cerebral cortex
pay attention to the body posture ring sleep. Generally, it is better to sleep in right position. When sleeping on your back, your hands and feet should be vertical naturally, and the pillow should not be too high. We should correct the bad habit of sleeping on the stomach. Hope to help you, wish you a good dream
friend, dream is a kind of enjoyment, which can let you experience many things you can't experience, whether it's a dream or a nightmare, it doesn't have any special meaning. Please enjoy the gift from your brain, enjoy your dream, it's only your own world

3. The whole computer (stproof, high temperature proof, antimagnetic, moisture-proof, antistatic and shockproof) should be placed in a clean room to avoid the adverse effects of too much st on the computer accessories; Enough heat dissipation space should be reserved around the computer, and no sundries should be piled up; Do not smoke ring the computer work, and the damage of smoke to the computer should not be underestimated; There should be no strong magnetic field around the computer. The speaker should not be placed near the monitor as far as possible, and the disk, credit card and meal card should not be placed on the speaker to prevent it from being magnetized; Don't put a teacup on the computer desk, and don't put it on the host, monitor and keyboard. The computer is afraid of water. If you don't believe me, ask it, ha ha; Don't move or vibrate the main computer case in the computer work, mainly can't bring vibration to the hard disk; If the computer is not used for a long time, the power should be cut off, but it should be turned on regularly to drive away the moisture. In addition, more importantly, we should clean the computer regularly. Monitor can be said to be the most important and expensive accessory of a computer, and it is also the latest eliminated proct in a PC component, so its maintenance is more important. 1. If your monitor screen does not belong to the touch screen, do not touch the monitor screen with your hands, because there are many things you do not know on your hands that will cause damage to the screen, such as static electricity. During the use of the computer, a large amount of static electricity will accumulate on the surface of the components. The most typical is that when the monitor touches the display screen with hands after use, violent electrostatic discharge will occur. Electrostatic discharge may damage the monitor, especially the fragile LCD. For example, grease, the surface of CRT screen is generally coated with anti glare anti-static (agas) coating, anti reflection anti static (ARAS) coating, and the grease on your hand will damage the coating on the surface of the display. Here, I would also like to say that when cleaning the CRT display screen, alcohol should not be used, because alcohol will dissolve this special coating. It is better to use flannelette or mirror wiping paper to insert and wash the screen. It is better not to use ordinary paper towel. 2. Do not place things with strong magnetic field (such as speakers) near the display, but the display will inevitably be affected by various electromagnetic waves, so the general display has degaussing function. We should degausse the display regularly (for example, for a month), but pay attention not to use this function repeatedly at the same time. 3. Don't put sundries on the monitor, such as tea cups, heavy objects, optical discs, mobile phones, etc., and don't block the cooling holes of the monitor shell. 4. Don't let your monitor be exposed to strong light (such as sunlight). Don't turn the monitor too bright or the contrast is too strong, so as to avoid premature aging of the filament and phosphor of the kinescope. 5. Don't open the monitor without permission. If you are not a professional, there is a high voltage circuit in the monitor. 6. Nowadays, LCD is becoming cheaper and more advanced, so more and more people use it. Compared with CRT, LCD is thinner and more fragile (especially its LCD panel). It is not advisable to point or poke the LCD with your hand, although it is not a big problem for CRT, But the LCD display is different. It may scratch the protective layer, damage the liquid crystal molecules of the display, and greatly rece the display effect. Therefore, this bad habit must be corrected. After all, your LCD display is not a touch screen. If you can, spend more than ten yuan to buy a protective film to stick on the LCD surface (you may feel that the brightness becomes low); In addition, strong impact and vibration should be avoided. If the screen and sensitive electrical components in LCD display are subjected to strong impact, they will be damaged. For LCD display, remember not to sprinkle water directly on the surface of the display. Water entering the LCD will cause short circuit of the screen. Do not keep the LCD on for a long time (continuous for more than 72 hours). If it is used continuously for a long time, the LCD panel will be heated, aged or the components will overheat. Host 1. Do not open the chassis to run. It is true that opening the chassis cover can cool the CPU, but the negative impact is even greater. Generally, the chassis is designed with holes in the front and back (be careful not to block these holes), so as to form air convection inside the chassis, so that all internal parts can be cooled. Do not think that only the CPU will heat, You know, there are no electronic procts that don't heat up. I believe everyone has studied physics. Besides CPU, the heat output of hard disk and optical drive can't be underestimated. Nowadays, the speed of mainstream hard disk is 7200 rpm. Just think about it; There is also a CD-ROM. you can take a CD-ROM and run for one minute, then take it out to feel the temperature. If you open the cover of the case, the convection inside the case will be lost, which will make the heat generated by the hard disk and the circuit board at the bottom of the CD-ROM drive go up, not only can't be dissipated, but also can be used to heat yourself; The boot case cover will also bring electromagnetic radiation, noise and other hazards. First of all, it is not good for your health, and it will make the accessories in the case more likely to be dirty, bring electrostatic hazards, and hinder the rotation of the fan; In addition, it will also bring hidden dangers to the accessories inside the chassis. In case of water spilling inside, the consequences will be unimaginable. If you want to kill your desktop computer, you can take it for a cross-country drive, or take it on your back to climb mountains or dance disco, which will be faster; Your vibration is too small, it will take a long time to achieve results. If you are willing to stick to it, it is estimated that the first achievement you have achieved is to proce a successful hard disk. The cause of death is the bad way of hard disk It is not allowed to mix screws and other conctors in the chassis, otherwise it is very easy to cause short circuit of the board and card in the chassis, resulting in serious consequences. 4. When you want to open the chassis panel to maintain the hardware in the host. You should first cut off the power and put your hand on the water pipe for a while to let off the static electricity. First, unplug the connection between the host and other peripherals, disassemble the chassis, check whether there are abnormal traces in the equipment, and timely use a soft brush or cloth to wipe the st in the chassis (motherboard, graphics card, sound card, power fan, etc.). If you know a little bit about hardware, it is recommended that you plug and unplug all hardware regularly. 5. The messy data cable and power cable inside the host can be tied up with rubber band, which not only gives people a clean feeling, but also facilitates the heat dissipation of the host. Motherboard usually doesn't open the chassis, so we can't touch it very much. What I encounter most is that some people often unplug or plug in the mouse and keyboard of PS / 2 interface when they turn on the computer. In fact, this is very dangerous. The interface is broken (it costs dozens of yuan to replace it), or the related chip or circuit board is burned. On ordinary computers, only USB interface and IEEE 1394 FireWire interface are commonly used to support hot swap. In addition, the plug interface should be pulled out parallel to the horizontal plane to prevent physical deformation of the interface. Compared with the hard disk, the hard disk belongs to a very fragile category. If the hard disk is not well protected, it is easy to have problems. On the one hand, vibration is the main killer, so do not move the host when the computer is running; Another is the habit of using. When the hard disk is running at high speed (the red light on the chassis panel flashes), never restart the computer or cut off the power directly; If you dismount the hard disk, the right way to hold the hard disk is to hold both sides. It is best not to touch the circuit board on the back, because the static electricity on the hand may damage the circuit board (especially when the climate is dry). CPU 1. Now the running frequency of mainstream CPU is fast enough. There is no need to use it over frequency. On the contrary, it should be reced in summer. In addition, it is not necessary to be too sensitive to the temperature of CPU. Some friends are scared when they see 50 or 60 degrees. In fact, there is no exaggeration. Generally speaking, the CPU can work safely below 75 degrees (generally speaking, the safe working temperature = 80% of the limit working temperature). 2. When it comes to CPU, we have to talk about CPU fan. Most people don't pay much attention to it. They think it's just a fan, but it's the patron saint of CPU. Considering the current heating level of mainstream CPU, if there is no CPU fan, the CPU will be burned in a few minutes. Therefore, we should pay attention to the operation of CPU fan, It is also necessary to remove the st on the fan blades and add lubricating oil to the fan bearings from time to time. 3. If you want to install the CPU, pay attention to the direction of the CPU socket. There is a pin hole missing on each corner of the socket, which corresponds to the CPU. When installing the CPU radiator, make sure to evenly apply a layer of thermal conctive adhesive on the CPU core first, not too thick, so as to ensure full contact between the radiator and the CPU core. Do not use brute force ring installation, so as not to crush the core. After installation, be sure to connect the fan power supply (there is a three pin power interface for CPU fan on the motherboard). 4. In case your CPU fan is broken, you'd better choose the original CPU fan or Kyushu Fengshen and other regular manufacturers when you replace it. Never buy a fan without quality for the sake of cheapness. Memory 1. When only one memory needs to be installed, the memory socket close to the CPU socket should be preferred. The advantage of this is that when the memory is polluted by the st from the CPU fan, it can be cleaned, but the socket is not easy to clean. 2. About the problem of memory mixing, when upgrading the memory, try to choose the same memory as your existing one. Don't think that buying a new mainstream memory will make your computer perform a lot. On the contrary, there may be many problems. Memory mixing principle: insert the low standard and low standard memory into the first memory slot (dimm1). 3. Install the memory mole. There are two teeth on both sides of the DIMM slot. When the memory gap is aligned correctly and inserted in place, the two teeth should automatically "bite" the memory. There is only one notch on the golden finger of DDR memory, and the two sides of the notch are asymmetric, corresponding to a ridge on the DIMM memory slot, so the direction is easy to determine. For the former SDR, there are two gaps, and it's easy to determine the direction. However, SDR has graally faded out of the market, so it's OK to know about it; When you pull up the memory, you only need to move two teeth outward, and the memory will automatically come out of the DIMM (or RIMM) slot. 4. For the failure of memory gold finger and graphics card oxide layer caused by st, we should use rubber or cotton dipped in alcohol to clean, so that the screen will not be black. Drive (CDROM, CDRw, DVD ROM, combo, DVD RW) 1. I'm still talking about shockproof, st-proof, moisture-proof and heat dissipation. In fact, we should pay attention to these for any computer accessory. 2. Don't always leave the CD in the CD-ROM drive, because the CD-ROM drive will be detected every once in a while, especially the recorder, which is always detecting the CD-ROM drive. When the high-speed CD-ROM drive (especially the CD-ROM drive 52X) works, the motor and control components will proce high heat, which will increase the temperature of the whole machine, On the other hand, it also accelerates the wear of mechanical parts and the aging of laser head. 3. Don't put the discs in it. They are not VCDs. In fact, the error correction ability of computer drivers is far less than that of VCDs. It's not necessary to watch movies
4. Every day I think, every night I dream. Dream of digging a lot of gold, it is just a dream, there is no substantive problem, so for people who are easy to dream, do not mind what, everything is natural.
5. Dreaming of gold is a sign of failure
dreaming of gold indicates setbacks. Dream of someone to send gold to themselves, may suffer losses. A woman's dream of losing gold indicates the purchase of new jewelry
dream of a day when you find gold and know what you need! Today is a critical day for your growth. There is always an opportunity to touch your thoughts on personal development and help you find out what is the driving force in your life. Is it a sense of security, a sense of achievement, or pure material enjoyment? You might as well give yourself some time to be alone today and listen to your inner voice
pregnant people dream of finding gold and giving birth to a daughter. More maintenance
people in love dream that they have g up gold and someone has damaged it. Handle it carefully and don't misunderstand each other
people in their own year dream that they have g up gold, and that they have changed their address or career, and that success will come later
business people dream that they have g up gold. Although they have money to gain, they should not be careless, otherwise they will lose a lot.

7. 1 Note when using the computer:
1. Use the computer in a clean environment. Computer is a kind of high-tech procts, its use environment is relatively broad, but if the working environment is not good, the computer will fail. If the floppy drive cannot read the information, it is likely that the magnetic head is stained with st. Therefore, the author suggests that we should use the computer in a clean environment. If we don't use it for a long time, we should cover the computer with a st proof cloth to prevent the occurrence of falling st
2. Work at proper temperature. If the temperature of the environment around the computer is too low or too high, the computer will not work normally. After some users turn on the machine, in order to prevent st, they still use the st cloth cover on the computer. This will cause the temperature inside the computer to rise graally, which will have a bad impact on the computer. In addition, when placing, the computer should be at least 15 cm away from the wall, which can not only ensure that all kinds of cables connected at the back of the machine will not be accidentally broken, but also make the hot air extracted by the fan in the chassis quickly diffuse, so as not to make the temperature inside the host rise too fast
3. The position of the computer should be firm. After the computer is stable, it is better not to move it at will when it is turned on, so as not to damage the hard disk
4. Prevent the accumulation of static electricity. At this point, we should have a deep understanding that when the weather is dry, or fiber friction is easy to proce static electricity, when the accumulation of static electricity is too much, it will affect the computer to correctly execute program instructions, and even burn the internal chip of the computer. Therefore, the computer must have a reliable grounding setting, or maintain a certain humidity of the air in the use environment
5. It's better for the computer to use the power supply from the line separately, and don't share the same line with other electrical appliances (such as air conditioner, refrigerator, color TV), so as to prevent the current generated by these electrical appliances from causing damage to the computer. Conditional users can additionally configure regulated power supply or UPS uninterruptible power supply
6. Do not plug in or out the connection between other devices and computers. Because when the computer is powered on, a high voltage will be generated on these interface components. If it is plugged in and out casually, the high voltage will probably burn the interface components. Therefore, if you need to remove or connect the connection between the computer and other devices, you should first turn off the power, and then plug
(2) maintenance of computer hardware
in the current computer system, CPU, graphics card chip, power supply and so on, the heat emitted by these components when the computer is working will greatly increase the temperature in the chassis and rece the performance of the system. Therefore, we need to pay attention to the heat dissipation of components when we use the computer at ordinary times
nowadays, the most common way of cooling computer is air cooling, that is, using the air from the fan to cool the components. Among them, the CPU has a fan, the graphics card has a fan, and the power supply has a fan. If it is an air ct chassis, there are more fans. After using the computer for a period of time, the performance may be lower than when I bought it. Generally, the main reason is that the cooling capacity of the system is reced
in general, the cooling fan of a computer will be lost after long-term use, which will rece the speed of the fan and the cooling capacity. But I think the reason is more e to the st accumulated inside the chassis. Imagine that so many fans in the chassis extract air from the outside to cool the internal devices, and there are many st particles in the extracted air. If the surface temperature of the components inside the computer is higher than that of the extracted air, Then these st particles are easy to be adsorbed on the surface of the device, and the st is also easy to gather on the blade of the cooling fan. Over time, st will form a layer of st film on the surface of components, which will directly affect the heat dissipation effect of each component. In addition, the st adsorbed on the fan blade will also increase the weight of the fan blade, resulting in the decrease of the fan speed and the cooling capacity of the system
as the st inside the computer becomes thicker and thicker on the board inside the computer, the st will accumulate on the exposed pins of the internal parts of the computer. Especially in this season, the air will be humid, and the st will form a plate with moisture on the board. The accumulated st will form a conctor at this time, which will short circuit the board. In serious cases, the parts may be burned. It can be seen that the decline of heat dissipation capacity is the most basic reason for the decline of system stability, so it is very necessary to regularly remove st inside the computer
before cleaning up the st inside the computer, make sure that the power supply of the computer is completely cut off. It is better to unplug all the power supply and other connecting wires. If you have a vacuum cleaner, you can first use the vacuum cleaner to roughly suck the inside of the chassis, then remove all the components inside the chassis, and use a brush to clean up the st on it. It is worth noting that most of the st is concentrated at the bottom of the radiator. This is because the bottom of the radiator is in contact with the surface of the CPU, and the temperature is the highest, so it is easy to absorb st. As the general radiator is fin shaped, it will be more troublesome to remove st inside. Fortunately, the current radiator is made of copper or aluminum, which is not easy to rust, so the effect will be better if the radiator is washed with clean water
after cleaning, install all the components, and then turn on the computer to see if it works normally. I believe that the performance of a computer without any burden will be as good as when I bought it
(3) computer software maintenance
1. We usually do a good job of file backup for the maintenance of computer software. This work is very important, because in the normal operation of the computer, sometimes accidentally wrong file, serious words will lead to unexpected consequences. If you had done a backup in advance, it would have been safe
2. Prevent computer virus. Once the computer virus enters the computer, it will cause losses to users. Usually, you can use anti-virus software to check whether there is a virus in the computer. If it is found that the computer does have a virus, you can use anti-virus software to remove it. You can also restore the backup data to the hard disk and cover the infected files
3. Don't use shareware frequently. At present, shareware is mostly some personal proction software that can be tried for free. Because it is a free trial, shareware will soon become popular. However, there is no authoritative evaluation standard for the quality of personal software, and users may prefer some functions of a sharing software and use it for a long time. However, after a period of time, it may be the time when the system is about to crash when the bug of the sharing software is found. In addition, sharing software is also likely to become the media of Trojan virus and other dangerous codes. Trojan virus can cause the performance of the controlled computer to be extremely unstable, and it can also steal the data on the controlled computer
4. Try to make the computer system use the certified WHQL driver. WHQL driver is the certification laboratory of Microsoft for computer hardware and driver. Any driver certified by WHQL laboratory means that the availability of the computer hardware installed on the computer with Windows operating environment is quite high. That is to say, after passing the WHQL certification of Microsoft and the hardware driver of a certain computer, it indicates that the driver can work well in most operating systems under very bad conditions
5. Do a good job of disk arrangement frequently. For the working principle of the computer itself, whenever the user creates and deletes files or folders, installs new software or downloads files from Ineternet, the "volume" on the disk will form fragments. The more fragments in the "volume" on the disk, the lower the file input and output performance of the computer system, which leads to the block of the system, Affect the stability of the whole computer system, so the best solution is to use disk cleaning program to do the cleaning work of computer disk.

However, there is no authoritative evaluation standard for the quality of personal software, and users may prefer some functions of a sharing software and use it for a long time. However, after a period of time, it may be the time when the system is about to crash when the bug of the sharing software is found. In addition, sharing software is also likely to become the media of Trojan virus and other dangerous codes. Trojan virus can cause the performance of the controlled computer to be extremely unstable, and it can also steal the data on the controlled computer
4. Try to make the computer system use the certified WHQL driver. WHQL driver is the certification laboratory of Microsoft for computer hardware and driver. Any driver certified by WHQL laboratory means that the availability of the computer hardware installed on the computer with Windows operating environment is quite high. That is to say, after passing the WHQL certification of Microsoft and the hardware driver of a certain computer, it indicates that the driver can work well in most operating systems under very bad conditions
5. Do a good job of disk arrangement frequently. For the working principle of the computer itself, whenever the user creates and deletes files or folders, installs new software or downloads files from Ineternet, the "volume" on the disk will form fragments. The more fragments in the "volume" on the disk, the lower the file input and output performance of the computer system, which leads to the block of the system, Affect the stability of the whole computer system, so the best solution is to use disk cleaning program to do the cleaning work of computer disk.
8. Computer maintenance methods: the whole machine (st, high temperature, magnetic, moisture, static and shock proof) computer should be placed in a clean room to avoid too much st causing adverse effects on the computer accessories; Enough heat dissipation space should be reserved around the computer, and no sundries should be piled up; Do not smoke ring the computer work, and the damage of smoke to the computer should not be underestimated; There should be no strong magnetic field around the computer. The speaker should not be placed near the monitor as far as possible, and the disk, credit card and meal card should not be placed on the speaker to prevent it from being magnetized; Don't put a teacup on the computer desk, and don't put it on the host, monitor and keyboard. The computer is afraid of water. If you don't believe me, ask it, ha ha; Don't move or vibrate the main computer case in the computer work, mainly can't bring vibration to the hard disk; If the computer is not used for a long time, the power should be cut off, but it should be turned on regularly to drive away the moisture. In addition, more importantly, we should clean the computer regularly. Monitor can be said to be the most important and expensive accessory of a computer, and it is also the latest eliminated proct in a PC component, so its maintenance is more important. 1. If your monitor screen does not belong to the touch screen, do not touch the monitor screen with your hands, because there are many things you do not know on your hands that will cause damage to the screen, such as static electricity. During the use of the computer, a large amount of static electricity will accumulate on the surface of the components. The most typical is that when the monitor touches the display screen with hands after use, violent electrostatic discharge will occur. Electrostatic discharge may damage the monitor, especially the fragile LCD. For example, grease, the surface of CRT screen is generally coated with anti glare anti-static (agas) coating, anti reflection anti static (ARAS) coating, and the grease on your hand will damage the coating on the surface of the display. Here, I would also like to say that when cleaning the CRT display screen, alcohol should not be used, because alcohol will dissolve this special coating. It is better to use flannelette or mirror wiping paper to insert and wash the screen. It is better not to use ordinary paper towel. 2. Do not place things with strong magnetic field (such as speakers) near the display, but the display will inevitably be affected by various electromagnetic waves, so the general display has degaussing function. We should degausse the display regularly (for example, for a month), but pay attention not to use this function repeatedly at the same time. 3. Don't put sundries on the monitor, such as tea cups, heavy objects, optical discs, mobile phones, etc., and don't block the cooling holes of the monitor shell. 4. Don't let your monitor be exposed to strong light (such as sunlight). Don't turn the monitor too bright or the contrast is too strong, so as to avoid premature aging of the filament and phosphor of the kinescope. 5. Don't open the monitor without permission. If you are not a professional, there is a high voltage circuit in the monitor. 6. Nowadays, LCD is becoming cheaper and more advanced, so more and more people use it. Compared with CRT, LCD is thinner and more fragile (especially its LCD panel). It is not advisable to point or poke the LCD with your hand, although it is not a big problem for CRT, But the LCD display is different. It may scratch the protective layer, damage the liquid crystal molecules of the display, and greatly rece the display effect. Therefore, this bad habit must be corrected. After all, your LCD display is not a touch screen. If you can, spend more than ten yuan to buy a protective film to stick on the LCD surface (you may feel that the brightness becomes low); In addition, strong impact and vibration should be avoided. If the screen and sensitive electrical components in LCD display are subjected to strong impact, they will be damaged. For LCD display, remember not to sprinkle water directly on the surface of the display. Water entering the LCD will cause short circuit of the screen. Do not keep the LCD on for a long time (continuous for more than 72 hours). If it is used continuously for a long time, the LCD panel will be heated, aged or the components will overheat. Host 1. Do not open the chassis to run. It is true that opening the chassis cover can cool the CPU, but the negative impact is even greater. Generally, the chassis is designed with holes in the front and back (be careful not to block these holes), so as to form air convection inside the chassis, so that all internal parts can be cooled. Do not think that only the CPU will heat, You know, there are no electronic procts that don't heat up. I believe everyone has studied physics. Besides CPU, the heat output of hard disk and optical drive can't be underestimated. Nowadays, the speed of mainstream hard disk is 7200 rpm. Just think about it; There is also a CD-ROM. you can take a CD-ROM and run for one minute, then take it out to feel the temperature. If you open the cover of the case, the convection inside the case will be lost, which will make the heat generated by the hard disk and the circuit board at the bottom of the CD-ROM drive go up, not only can't be dissipated, but also can be used to heat yourself; The boot case cover will also bring electromagnetic radiation, noise and other hazards. First of all, it is not good for your health, and it will make the accessories in the case more likely to be dirty, bring electrostatic hazards, and hinder the rotation of the fan; In addition, it will also bring hidden dangers to the accessories inside the chassis. In case of water spilling inside, the consequences will be unimaginable. If you want to kill your desktop computer, you can take it for a cross-country drive, or take it on your back to climb mountains or dance disco, which will be faster; Your vibration is too small, it will take a long time to achieve results. If you are willing to stick to it, it is estimated that the first achievement you have achieved is to proce a successful hard disk. The cause of death is the bad way of hard disk It is not allowed to mix screws and other conctors in the chassis, otherwise it is very easy to cause short circuit of the board and card in the chassis, resulting in serious consequences. 4. When you want to open the chassis panel to maintain the hardware in the host. You should first cut off the power and put your hand on the water pipe for a while to let off the static electricity. First, unplug the connection between the host and other peripherals, disassemble the chassis, check whether there are abnormal traces in the equipment, and timely use a soft brush or cloth to wipe the st in the chassis (motherboard, graphics card, sound card, power fan, etc.). If you know a little bit about hardware, it is recommended that you plug and unplug all hardware regularly. 5. The messy data cable and power cable inside the host can be tied up with rubber band, which not only gives people a clean feeling, but also facilitates the heat dissipation of the host. Motherboard usually doesn't open the chassis, so we can't touch it very much. What I encounter most is that some people often unplug or plug in the mouse and keyboard of PS / 2 interface when they turn on the computer. In fact, this is very dangerous. The interface is broken (it costs dozens of yuan to replace it), or the related chip or circuit board is burned. On ordinary computers, only USB interface and IEEE 1394 FireWire interface are commonly used to support hot swap. In addition, the plug interface should be pulled out parallel to the horizontal plane to prevent physical deformation of the interface. Compared with the hard disk, the hard disk belongs to a very fragile category. If the hard disk is not well protected, it is easy to have problems. On the one hand, vibration is the main killer, so do not move the host when the computer is running; Another is the habit of using. When the hard disk is running at high speed (the red light on the chassis panel flashes), never restart the computer or cut off the power directly; If you dismount the hard disk, the right way to hold the hard disk is to hold both sides. It is best not to touch the circuit board on the back, because the static electricity on the hand may damage the circuit board (especially when the climate is dry). The best way to transport the hard disk is to install an anti-static bag, and then use foam protection to minimize vibration.

9. Check the appearance of the air inlet and try to install a st screen. Dust net net 10 yuan a sheet, after cutting their own way to cover the air inlet. It can be cleaned every 2 weeks every month. There is also the fan stproof net, which covers the air inlet surface of the fan and has a fixed size. However, it's a little inconvenient because it needs to open the case every time it's disassembled and washed. My Dell dimension 5150 is a stproof net pasted on the air inlet. Because the air inlet has a special shape, it can be jammed without reinforcement. If you can't get stuck, think of a way, such as cellophane or rubber band and paper clip. Of course, it may affect the appearance.
