If you don’t play until you die—“you won’t stop until you die”! Do you have to play until you freeze? We have reached this step, why don't you carefully check the source of your crash? Just like water flow, any blockage failure at any point in the entire process will cause a shutdown. The following aspects are the root causes of this phenomenon. You may wish to check carefully, completely and thoroughly according to the following aspects; your problem will be solved. ★Copyright statement: This answer is the original work of Harmony and no one may steal it! ★1: Power supply 1.1 Use a multimeter to check whether the power supply is stable? 1.2 Is the AC voltage fluctuation within the allowable range? Does it exceed 5% of the rated voltage? 1.3 Is the ripple coefficient of the A/D power supply qualified (checked with a millivolt meter)? 1.4 Is the temperature rise of the power supply abnormal? 1.5 Do the voltage stabilization characteristics meet the technical specifications? 1.6 Do the voltage stabilization characteristics and ripple coefficient under rated load meet the technical specifications? 1.7 When replacing a larger fan, does your power supply capacity meet the requirements? 1.8 The power supplies of general auxiliary equipment (routers, network switches, modems, etc.) are rectified power supplies without voltage stabilization function. The ripple coefficient is large (may be caused by drying up of the filter capacitor) and the load capacity is also poor; special attention should be paid. 1.9 Due to equipment overvoltage (just like feeding a child, if you feed a child too much, you will die), low voltage (like feeding a child, if you feed a child too little, you will be malnourished), and excessive voltage fluctuations (just like feeding a child, one meal when hungry and one meal when full). (indeterminate amount of pauses), overcurrent, and heat, causing the overheating protection action to cut out a fault and remove the equipment from operation (i.e., slow, delayed, repeated starts, delays, dropped calls, interruptions, disconnections, automatic shutdowns, crashes, etc.) Display image), etc.; 1.10 Does the overcurrent protection and overheating protection of the power supply operate correctly? Is the action sensitive? Does it refuse to move or move by mistake? 2: Check the network cable and crystal head (R45): 2.1 Are the crystal head and socket plugged in properly (are they loose)? 2.2 Is the contact good? What is the contact resistance? 2.3 Is there any dust accumulation? Is it oxidized? 2.4 Is the mechanical lock between the crystal head and the base locked? 2.5 Is the locking firm? 2.6 Are the network cable and crystal head pressed tightly and in good contact? 2.7 The line-to-line insulation resistance of the network cable (using a 100V megger) should be greater than 20 megohms. ★Copyright statement: This answer is original to Harmony and no one may steal it! ★3: Lightning protection and grounding: Grounding is mainly to ensure the safety of people and equipment! Lightning strikes will burn the network card; in severe cases, it can cause fires and casualties! The principles are multi-point grounding, repeated grounding, and nearby grounding; grounding is divided into protective grounding, shielding grounding, working grounding, etc.; Static electricity is the culprit causing a blue screen of crash! I used a noise meter to test that the noise voltage when not grounded was more than 6,000 times greater than the signal. If you are not grounded, can your equipment work with such high noise? Grounding is the most basic requirement for IT. This is true for analog equipment and even more so for digital circuits. Interference from all aspects can be reduced or eliminated through grounding, including external interference and inter-line coupling of local and local wiring. Reduce and eliminate, and do a good job of grounding and shielding the equipment. Many interferences come from poor shielding and poor grounding. Many people only work on software. Many interferences are caused by poor or no grounding. This kind of Faults are very easy to occur and are easily ignored by many people. Many equipment damages are directly related to grounding. No grounding or poor grounding will lead to inter-code interference, bit errors, delays, packet loss, intermittent, and disconnection (disconnection, interruption). ), crashes, stuck, automatic shutdown, repeated startup, repeated startup, frequent restart (or repeated connection) and other phenomena. There must be more than two grounding poles, with a minimum distance of more than 10 meters between each grounding pole. The grounding wires from the grounding poles to the computer room must not have any joints. They must be introduced into the computer room with soft copper wires with a cross-section of not less than 25 square millimeters. Bus bar (no joints are allowed in the middle), the ground wire is symmetrically connected to the Faraday net to facilitate the distribution of current. The connection point with the bus bar must be coated with silver powder conductive paste. The cross section of the ground wire from each device to the bus bar (independent) must not be Less than 4 square meters of multi-stranded soft copper wire, the ground resistance of the busbar to each ground electrode is less than 5 ohms (the smaller, the better). Use a grounding meter (a grounding meter measuring level 2.5 or above, and the meter is within the inspection qualification period) to check at least twice a year. When checking the grounding electrode, it is strictly prohibited to do it in thunderstorm weather. It is strictly forbidden to use the N neutral line of water pipes and power lines as grounding; that is, an independent grounding device. The wires of each device are independently connected to the bus in the computer room. It is strictly prohibited to connect them in series and then connect to the bus. I can say very subjectively: No matter you are an individual user or a collective user in a large computer room, you have no grounding at all (or the grounding is unqualified).

★Copyright Statement: This answer is an original work of Harmony and no one may steal it! ★4: Bandwidth: The bandwidth from the operator to the user is very important. Without enough bandwidth, sufficient data flow cannot be guaranteed; computer Internet access cannot be smooth; The bandwidth mentioned above refers to the bandwidth of the whole process. Just like on a highway, with such a wide bandwidth, there should be no fluctuations in the whole process; a slight fluctuation in the whole process will affect the network speed; users have the right to request the operator (use a frequency scanner) Test) to provide guarantee; 5: Signal-to-noise ratio: (the ratio of signal to noise, which can be understood as the purity of the signal) is small, the useful signal is covered up by noisy spurious signals (especially the code space between symbols) Interference), so that the receiving path cannot correctly extract useful signals from noisy signals, and the judgment circuit cannot correctly judge the code elements, resulting in bit errors. Serious bit errors are packet loss, and severe packet loss This is the cause of delay. Serious delay will cause disconnection (slowness, delay, repeated startup, disconnection, delay, disconnection, interruption, disconnection, automatic shutdown, crash, etc.). Use a noise meter. Or use a level meter to measure whether the noise level is within the allowable range, or use an oscilloscope to observe whether there are spurious signals? Is there inter-symbol interference between codes? Take measures to eliminate it. The signal-to-noise ratio should also be greater than 60dB. Test (observe) with a scanner and oscilloscope. This indicator is to ensure smooth and barrier-free roads. With such a wide road, it must be barrier-free throughout. 6: Matching: Matching includes level matching and impedance matching (tested with a level meter and signal generator) 6.1 Level matching: The received signal cannot be too low. If it is too low, the threshold level required for reception will not be reached. If the amplitude is too high, the equipment will not work properly; if the level is too high, the receiving circuit will be saturated or burned out. If the reception level fluctuates near the reception threshold, the computer will frequently restart; therefore, reception level adjustment is very important. During operation, always use a level meter or oscilloscope to monitor and adjust the reception level at the connection within a suitable amplitude range. Monitor adjustments with a level meter according to the instructions. 6.2: Impedance matching: The connection points must achieve relative impedance matching. Mismatching of input and output impedance will lead to reflection loss, and the signal will not work properly no matter how strong it is. 7: Optimize the network structure. When people turn on their computers and surf the Internet, they will generate garbage. Just like eating, if they do not clear the table, wash the tableware, or clean the stove, they will also generate computer garbage. The computer will gradually show symptoms of slowness, lag, delay, repeated startup, and disconnection. and other failures; therefore, I personally recommend using some small tools: such as Super Rabbit, Optimization Master, Master Lu or 360, etc.; develop a good habit of cleaning up garbage before going offline. 7.1: Clear the garbage fragments and IE cache generated by surfing the Internet in a timely manner: As long as you use the computer, garbage will be generated. If you don’t clean it up in time, it will accumulate more and more. If you don’t clean it up for a long time, the running C drive space will become smaller and more cluttered. , and finally gradually slows down until it crashes; therefore, regular cleaning and running of the C drive can maintain the computer's running speed.

7.2: Synchronize the ADSL device first: power off the device and then restart it. 8: Software settings and configuration 8.1: Try to download commonly used software from large official websites, and do not install 3, informal software, P2P (resource-consuming) software, and uncommon software. Turn off All unnecessary network connections and startup items, such as Thunder, BT, Donkey, etc.; do not put non-running software in the running c drive; update patches in real time. Game software should be downloaded from regular large-scale websites, and pay attention to whether the software is stable. Immature and unstable software will cause slowdowns, freezes, crashes and other failures, especially for some popular game software. Some netizens have strong reactions to this, so Pay special attention to the software or delete it immediately; when downloading software, pay attention to rogue software that takes the opportunity to insert and endanger the security of the computer, and remove it at any time. After some game software is started, the game will be shut down directly, and after it is restarted, it will experience infinite disconnections, restarts and other failures. Protocol: The protocol in the network must also match it. Mismatching may also cause some device failures. Software conflicts can also cause problems such as delays, lags, slowdowns, crashes, disconnections, and interruptions. 8.2: Anti-virus software and firewall: At least one effective and genuine anti-virus software and frequently upgrade the virus database: appropriate firewall settings (not too many, too high, too low) will cause some web pages to be unable to be opened; viruses can slow down the computer, Crash, disconnection, stuck, repeated startup and power on/off failure. 9: Temperature, humidity, temperature rise (the temperature gradually increases after booting). As the boot time prolongs, the temperature of the main device and its auxiliary devices (modem, router, network switch, etc.) will gradually rise. If If it cannot be distributed quickly, it will be delayed---slow---dropped---crash. 9.1: Humidity: In rainy seasons or rainy days and in high-humidity areas, the insulation between lines and devices decreases, and the signal level drops, resulting in computer code-to-code interference, bit errors, delays, packet loss, intermittent, and dropped calls (short lines or interruption), crash, automatic shutdown, repeated startup (repeated connection) and other phenomena, or unstable operation. Humidity accelerates oxidation, causing transmission interruptions.

9.2: Temperature (recently, with the gradual increase in temperature, faults caused by temperature will gradually increase): From the beginning of startup, the temperature will gradually increase. When the temperature rises to a certain level, it will stabilize. At this value, the difference between this value and the ambient temperature should not be greater than 25 degrees; since computers are semiconductor devices, the actual temperature of the device must not be higher than 85 degrees; when the chip temperature is close to 80 degrees, measures must be taken to reduce the temperature of the modem, router, network Operating environment temperature of switches and computer equipment. If the computer exceeds this range, it will cause inter-code interference, bit errors, delays, packet loss, intermittent, disconnection (disconnection or interruption), crash, automatic shutdown, repeated startup (frequent connections) and other phenomena. 9.3: Temperature rise (the difference between the actual temperature of the device and the ambient temperature is called the temperature rise). Temperatures less than 25 degrees Celsius have a great impact on the normal operation of the device, especially when the temperature rise of network switches, routers, computer motherboard chips, network cards, etc. is large. The equipment will be unable to operate; especially portable (also called notebook) computers, which have difficulty dissipating heat due to temperature rise due to the design priority of volume. They are most prone to inter-code interference, bit errors, delays, packet loss, and interruptions caused by temperature rise. Continuation, disconnection (short line or interruption), crash, automatic shutdown, repeated startup (repeated connection) and other phenomena. The measures are as follows: a: Place the equipment (referring to: Hubble, modem, router or network switch, computer, etc.) in a place that is safer for people. First disconnect the power supply, then open the cover of the equipment, and use air convection to enhance the connection with the air. Contact for natural heat dissipation;

b: Install a micro fan on the device to increase air convection and force heat dissipation;

c: If you are in IT, I recommend You: After disconnecting the power supply, install heat sinks on the heating components of the device.

d: After the device is disconnected from the power supply, use a 3mm drill bit to drill multiple holes up and down the device to enhance air convection and improve heat dissipation conditions; e: Place the device in a ventilated and dry place, preferably in a (There are also insulating heat dissipation brackets on the market for notebooks.) Use the insulating heat dissipation bracket to support the device and dissipate heat naturally; f: After the computer is used for a long time, when the silica gel between the CPU and the heat sink dries up, the CPU will seriously heat up and produce Packet loss, delay, slowness, repeated startup, disconnection, interruption, disconnection, automatic shutdown, crash, etc. Reapply silicone and resume normal use.

g: Clear the garbage fragments and IE cache generated by surfing the Internet in a timely manner: As long as you use the computer, garbage will be generated. If you don’t clean it up in time, it will accumulate more and more. If you don’t clean it for a long time, it will cause the C drive to run. The space becomes smaller and smaller and disorganized, and eventually it gradually slows down until it crashes; therefore, regular cleaning and running of the C drive can maintain the computer's speed.

h: Let the ADSL device synchronize first: power off the device and then restart it. Users who frequently surf the Internet should open the device's shell after powering off for up to half a year (by the way, check whether the internal connections of the device are good, whether the memory module is loose, and whether the memory module is in good contact with the card slot? Are the plug-ins loose? Are they plugged in tightly? Are the connections Whether the points are firm and in good contact), clean the dust inside the equipment. 10: Wiring: The wiring process is based on the principle of minimum interference; the wiring is required to be neat and beautiful, with strong and weak signals separated, and high and low frequency signals separated. Unreasonable wiring will cause interference caused by coupling and crosstalk between lines, and lines cannot be entangled with each other. , it is best to use shielded (shielding layer is reliable and grounded) wires. These parasitic interference will reduce the signal-to-noise ratio of the computer and make it unable to identify useful signals, causing inter-code interference, bit errors, delays, packet loss, intermittent, and dropouts. Line (short line or interruption), crash, automatic shutdown, repeated startup (repeated connection) and other phenomena. ★Copyright statement: This answer is the original work of Harmony and no one may steal it! ★11: The motherboard's button battery If the battery capacity is insufficient or there is no power, the computer will not be able to be turned on or other malfunctions will occur. 12: ADSL users: multiplex computer signals with telephone lines, pay attention to the impact on the computer in the three states of picking up, hanging up, and ringing; since both computer and telephone signals are transmitted on the telephone line (multiplexed), both A certain degree of isolation (greater than 60dB) and defense must be provided between them (the bigger the better, the better). In particular, some informal telephones will affect the use of the computer. Thirteen: Timing failure: When the equipment fails at a fixed time, be careful to see if there are large factories or fixed-time electrical equipment starting, welding and other starting equipment around it and between its transmission paths. Fourteen: A better solution to the slow speed of win7 should be this: enter the Windows 7 control panel, find and open color management. In the color management dialog box that opens, switch to the Advanced tab and click Change system defaults in the lower left corner. Subsequently, the system will pop up a dialog box Color Management-System Default again. In this dialog box, also switch to the advanced options, and then uncheck the system default checkbox Use Windows Monitor Calibration? After modification, save the settings and exit.

Smooth; people with low quality will have frequent failures no matter how high the configuration is; just like when people wear clothes (Skit: Chen Peisi in Good Guys and Bad Guys: No matter how good you give him clothes, he can’t go up the grade!), the clothes are not of the same grade.
