The causes of this phenomenon are many (user configuration is certainly very important), not only from one aspect or several aspects of the reasons to find a comprehensive search; any aspect of the reasons for this phenomenon is to produce the root cause of the phenomenon, the problem is that you are passive results, as well as proactive, as early as possible, to reduce the problem; you may wish to go by the following aspects of the scrutiny of the = unclogging of the various pieces of equipment on the road, road dredged = your problem is not solved. ★ Copyright: This answer for the "harmony" original, no one shall steal! ★1: you first check the cable and crystal (R45) head: crystal head and seat is plugged (loose?)? Is the contact good? What is the contact resistance? Is there any accumulation of dust? Is it oxidized? Is the mechanical lock between the crystal head and the holder locked? Is the latch secure? Are the network cable and the crystal head pressed together and in good contact? The insulation resistance between the wires of the network cable (using a 100V rocking meter) should be greater than 20 megohms.　2: Check the power supply Use a multimeter to check whether the power supply is stable? Is the AC voltage fluctuation within the allowable range? Is the ripple coefficient (checked with a millivolt meter) after A/D conversion of the power supply qualified? Is the temperature rise of the power supply abnormal? Is the voltage stabilization characteristic in accordance with the technical specifications? Do the regulated voltage characteristics and ripple factor under rated load meet the specifications? Generally, the power supply of auxiliary equipment (routers, network switches, cats, etc.) is a rectified power supply without voltage stabilization, with a large ripple coefficient (which may be caused by the drying up of the filter capacitors) and poor load capacity; special attention should be paid to it. Due to equipment over-voltage (like feeding a child, more can hold up), low-voltage (like feeding a child, less will be malnourished), voltage fluctuation is too large (like feeding a child, hungry, full of a variable amount), overcurrent, heat, resulting in thermal protection action cut out the fault and the equipment out of operation (i.e.: it will produce a slow, delayed, repeated startups, delays, dropouts, interruptions, disconnections, (i.e.: will produce slow, delayed, repeated start-up, delay, dropouts, interruptions, disconnections, automatic shutdown, crash and other manifestations), etc.; consider heat dissipation to replace the high-power fan, you should consider whether the capacity of the power supply is a match, do not blindly replace. ★ Copyright: This answer for the harmony of the original, no one shall steal! ★3: grounding: grounding is mainly to protect the safety of people and equipment! Grounding is the most basic requirements to do IT, analog equipment is so, digital circuits are more so, interference from all sides can be abated or eliminated by grounding, foreign interference and local, interline coupling between the local wiring can be abated and eliminated, do a good job of grounding equipment shielding, a lot of interference from bad shielding, poor grounding, a lot of people are only doing work on the software, a lot of interference are Caused by poor grounding or no grounding, this failure is very easy to produce, but also easy to be ignored by many people, many equipment damage and grounding has a direct relationship, no grounding or poor grounding can lead to inter-code interference, misuse, delay, packet loss, intermittent, drop (disconnection, interruption), dead, card, automatic shutdown, repeated startups, repeat startups, frequent reboots (or repeated with the connection) and other phenomena. Grounding must have more than two grounding electrodes, each grounding electrode between the minimum interval of 10 meters or more, grounding electrodes to the machine room grounding line shall not have any joints, respectively, with a cross-section of not less than 25 square millimeters of soft copper wire introduced into the machine room sink (intermediate is not allowed to have any joints), grounding line and Faraday network symmetrically connected to facilitate shunt dispersal, and the sink to the point of connection to be coated with silver powder conductive paste, each device to the Sink (independent) of the grounding wire cross-section shall not be less than 4 square meters of multi-stranded soft copper wire, sink for each grounding electrode grounding resistance of less than 5 ohms (the smaller the better). At least two or more times a year using a grounding meter (2.5 level or higher grounding meter measurement, and the meter in the scope of the inspection qualification period) to check. When checking the grounding electrode, it is strictly prohibited to do so under thunderstorms. It is strictly prohibited to use the N-zero wire of the water pipe and power line as the grounding use; that is, the independent grounding device. The wire of each device is independently connected to the busbar in the machine room, and it is strictly prohibited to connect the busbar after series connection. ★ Copyright: This answer for the harmony of the original, no one shall steal! ★ 4: bandwidth: from the operator to the user's bandwidth is very important, there is not enough bandwidth, you can not guarantee enough data traffic; computer Internet access is not smooth; the bandwidth mentioned above refers to the full bandwidth, like the highway, there is so wide bandwidth, the whole process can not be the phenomenon of undulation; the whole process of a little bit of undulation will affect the speed of the network; the user has the right to request the operator (with a sweep meter test) Give protection; 5: signal to noise ratio: (signal to noise ratio, can be interpreted as the purity of the signal) is small, the useful signal is noisy spurious signals masked no (especially between the code elements of the code interference), so that the road to receive the letter can not be correctly extracted from the noisy signals in the useful signals, the judgment circuit can not be correctly judged on the code elements, will produce a mis-code, a serious mis-code is a loss of packets, a serious loss of packets is the cause of delay. Packet loss is the cause of delay, serious delay will be the dropout (will produce slow, delayed, repeated start, dropout, delay, dropout, interrupt, disconnect, automatic shutdown, shutdown, and other manifestations, etc.), the use of a noise meter or level meter to measure the noise level is within the permissible range, or with an oscilloscope to observe the presence of spurious signals? Is there any inter-code interference between codes? Take measures to eliminate. The signal-to-noise ratio should also be greater than 60dB or more. Test (observe) with frequency sweeper and oscilloscope. This indicator is to ensure that the road is flat and free of obstacles. There is so wide road, but also the whole process without obstacles. 6: Matching: Matching including level Pi matching and impedance matching (with a level meter and signal generator test) 6.1 Level Matching: Received signals can not be too low, too low, up to the threshold level needed to receive the road amplitude, the equipment can not work properly; level is too high will make the road to receive the preamplifier circuit saturated or burned out the preamplifier circuit. Receive level fluctuations in the receiving threshold near the computer will make frequent repetitions of the restart phenomenon; therefore, the receiving level adjustment is very important. Operation should always use a level meter or oscilloscope to monitor and adjust the reception level of the connection in the appropriate amplitude range. According to the manual, the level meter monitoring adjustment. 6.2: impedance matching: the connection point must do the impedance relative matching, input and output impedance mismatch will lead to reflective attenuation, the signal and then the strongest can not work properly. 7: optimization of the network structure People turn on the computer to access the Internet will produce garbage as eating, do not clean up the table, do not scrub tableware, do not clean up the cooker, the same will produce computer garbage, the computer will be Gradually manifested as slow, card, delay, repeat startup, drop and other faults; therefore, I recommend the use of some small tools: such as Super Rabbit, Optimizer, LU Master or 360, etc.; to be cleaned up before getting off the line to be a good habit of garbage. 7.1: Timely removal of Internet generated garbage debris and IE cache: as long as you use the computer will produce garbage, do not clean it up in a timely manner, the more it accumulates more and more, for a long time without cleaning it up will make the C drive work. If you don't clean it up, it will make your C drive less and less spacious and cluttered, and then it will gradually slow down until it crashes; therefore, organizing your C drive regularly will keep your computer running at a high speed.

7.2: first let the ADSL device synchronization: the device is powered off and then restarted. 8: software settings and configuration 8.1: commonly used software download software as far as possible to the big official website to download, to do the 3 do not install, informal software is not installed, P2P (resource-hogging) software is not installed, do not install the software is not commonly used. Turn off all unnecessary network connections and startup items, such as Xunlei, BT, donkeys, etc.; non-running software should not be placed in the running c disk inside; real-time update patches. Game software to pour formal large-scale website to download, pay attention to whether the software is stable, immature, unstable software will lead to slow, card, crash and other failures, especially some of the public like the game software, some netizens reflect this very strongly, such software, pay special attention to or immediately delete; download software, pay attention to the hooligan software take the opportunity to insert the crisis of the computer's security, at any time to give the removal. Some game software after the start of the game will be directly T off, up will be unlimited after the drop. Software conflict will likewise cause delays, card, slow, dead, dropped, interruptions and other problems arise.8.2: antivirus software and firewall At least one effective and genuine antivirus software and often upgrade the virus database: firewall settings are appropriate (do not be too much, too high, too low); viruses can make the computer slower, dead, dropped, card, repeated startup and switching failures.9: Temperature, humidity, temperature rise (after the power on) Temperature in the gradual increase) With the prolongation of the boot time, the temperature of the main device and its auxiliary (cats, routers, network switches, etc.) devices, it will gradually rise, if it can not be quickly emitted, it will be delayed by the - - - - - - - - slow - - - - - - drop ---- dead. 9.1: humidity: rainy seasons or rainy days and its high humidity areas, the line and the insulation between the device is reduced, the signal level falls, resulting in the Computer inter-code interference, error code, delay, packet loss, intermittent, dropped (short or interrupted), dead, automatic shutdown, repeated startup (repeated connection) and other phenomena, or unstable work. Humidity accelerates oxidation, resulting in transmission interruption.

9.2: Temperature (especially in summer, high daytime temperatures, low nighttime temperatures): From the beginning of the boot, the temperature has the ambient temperature in the gradual increase in temperature to a certain point, it will be stabilized in the value of this value and the difference between this value and the ambient temperature should not be greater than 25 degrees, due to the computer belongs to the semiconductor device, therefore, requires that the device temperature shall not be higher than the actual temperature of 85 degrees; the chip temperature is close to 80 degrees. To take measures to reduce the cat, router, network switches and computer equipment operating environment temperature. If this range is exceeded, the computer will produce inter-code interference, error codes, delays, packet loss, intermittent, dropped (disconnected or interrupted), crash, automatic shutdown, repeated startup (frequent connection) and other phenomena. 9.3: Temperature rise (the difference between the actual temperature of the device and the ambient temperature is called temperature rise) is less than 25 degrees Celsius Temperature has a great impact on the normal operation of the equipment, especially network switches, routers, computer motherboards, chips, network cards and other temperature rise. Chip, network cards and other large temperature rise, the equipment will not be able to run; in particular, portable (also called laptop) computers, due to the design of the priority consideration of the volume of the temperature rise of the heat dissipation is difficult, the most likely to occur due to temperature rise of the inter-code interference, error codes, delays, packet loss, intermittent, dropped (short or interrupted), crash, automatic shutdown, repeated startup (repeated connection) and other phenomena. Measures are as follows: a: the equipment (refers to: Hubble, cats, routers or network switches, computers, etc.) placed in a safer place for people, the first disconnect the power supply, and then open the box cover of the equipment, the use of air convection to strengthen the contact with the air, the natural heat dissipation;

b: to the equipment to add a miniature fan to increase the convection of air, forcible heat dissipation;

c: if you do IT, I suggest you: after disconnecting the power supply, add heat sinks to the heated parts of the equipment.

d: after the equipment is disconnected from the power supply, use a 3 mm drill bit to drill more holes on the top and bottom of the equipment to strengthen the air convection and improve the heat dissipation conditions; e: the equipment to a ventilated and dry place, it is best to make a (also available on the market for laptops) insulated cooling bracket to support the equipment for natural heat dissipation; f: after the computer is used for a long time, when the silica gel between the CPU and the heatsink dries up, the CPU will be serious heat, will produce packet loss, delay, slow, repeat startup, drop, interrupt, disconnect, automatic shutdown, crash and other phenomena. To avoid this issue, please reapply the silicone rubber to the CPU and return to normal operation.

g: timely removal of Internet generated garbage debris and IE cache: as long as you use the computer will produce garbage, do not clean up in a timely manner, the more it will accumulate more and more, a long time to not clean up the C disk space will make the operation of the C disk space is getting smaller and smaller and cluttered, and finally gradually slow down until the computer is dead; therefore, the regular operation of the C disk can be organized, can keep the computer running speed.

h: First, let the ADSL device synchronization: power off the device and restart. Frequent Internet users up to six months, to power off and open the device's shell (by the way, check whether the device's internal connections are good, whether the memory stick is loose, the memory stick and card slot contact is good? Are the plug-ins loose? Is the plug tight? Whether the connection point is firm and good contact), clean up the dust inside the device. Ten: wiring: wiring process to minimize interference as a principle; require wiring neat and beautiful, strong and weak signals to go separately, high and low-frequency signals to go separately, the wiring is not reasonable will produce coupling between the lines, crosstalk interference caused by the line can not be entangled with each other, it is best to use shielding (shielding layer is reliable and grounded) line, these parasitic interference will make the computer signal-to-heterodyne ratio is reduced and can not recognize the useful signals, so that it produces inter-code interference, BER, delay, packet loss, intermittent, drop (short or interrupted), crash, automatic shutdown, repeated startup (repeated connection) and other phenomena. ★ Copyright: This answer for the harmony of the original, no one shall steal! ★ XI: the motherboard's button battery Battery capacity is not enough or no power, will also not be able to boot or produce other faults. XII: ADSL users: multiplexing computer signals with the telephone line, pay attention to the impact of the three states of the pick-up, hang-up, ringing on the computer; due to the computer and telephone signals are in the telephone line (multiplexing) transmission, the two must provide a certain degree of isolation between them (greater than 60dB), the degree of defense to be greater than 60dbB the greater the better), especially some informal words will affect the computer's Use. Thirteen: timed failure: equipment failure at a fixed time, to carefully around and between its transmission path whether there is a large factory or fixed time large electrical equipment start, welding and other start-up equipment. XIV: Win7 slow solution to a better way should be this: go to the Windows 7 Control Panel, find and open the color management. In the Color Management dialog box that opens, switch to the Advanced tab and then click Change System Defaults in the lower left corner. After that, the system will pop up a dialog box Color Management - System Defaults again. In this dialog box, also switch to Advanced Options, and then uncheck the system default check box Use Windows monitor calibration? After the modification, save the settings to exit. ★ Copyright: This answer for the harmony of the original, no one shall steal! ★ As long as you carefully in accordance with the above to do, and keep often do, general (my computer) configuration (128M memory, CPU frequency 1.6G) 512Kbit broadband, play the average mid-range games are very smooth; otherwise: configure even higher computers will be the same as frequent failures; like a person to wear clothes (skit: the good guys and the bad guys of the Chen Pesi: you give him good clothes, he can't even get into the class!)
