Causing this phenomenon to produce a lot of reasons, you may wish to follow the steps below to carefully check to find out the cause of the problem = dredge the road of each device, the road dredged = your problem is not solved. A: Is the power supply voltage? Is the power supply voltage stable? In your computer and its auxiliary equipment around and transmission part of no electromagnetic interference, especially welding machines and large loads of frequent start-up of the equipment. Effective power cord cross-section; safety insulation level in accordance with national standards. B: Dry and ventilated at a suitable temperature (add a fan or air conditioning system if necessary), C: Smaller dust particle size, walls and their roofs should preferably be painted. D: . The transmission part should have a high signal-to-noise ratio. E: Network card issues: appropriate bandwidth of the network card, stable work. F: software settings reasonable; ★ Copyright: This answer for the "harmony" original, no one shall steal! ★ I: the impact of temperature (especially in the summer daytime high temperatures, low temperatures at night): to take measures to reduce the cat, routers, network switches and computer equipment operating environment temperature. II: grounding system: according to the regulations (grounding device construction GB50169-92) requirements: grounding must have more than two "independent" (can not be communal "ground") of the grounding electrode, grounding electrode to the location of the lead cross-section is not less than 16 square millimeters of the Multi-stranded copper wire, each "independent" grounding pole grounding resistance shall not be greater than 5 ohms. User line shielding layer immediately grounded, the interference will be reduced to a minimum; water pipes and electricity (N line) ground can not be used as a grounding pole, the grounding wire can not be twisted, to be coated with silver powder conductive paste, with screws fastened. Lightning: to disconnect all lines connected to the outside world to avoid equipment personal accidents, so as to avoid fire accidents. Third: the system is clean: people wear clothes does not lie in the grade of the clothes, but in whether the clean and tidy; configuration is not high computer, you can also work to make you very satisfied; you do not do things in accordance with the objective law, configure even higher computers will be the same as frequent failures; like people wear clothes, clothes are not in the grade of high and low clean and sharp is good. This is to spend more money can not buy! Therefore: A: legitimate software, upgrade patches in a timely manner; delete unused files, timely clean up Internet garbage and regular defragmentation, optimization of the system structure; B: legitimate and effective antivirus software, and often upgrade the virus database; firewalls, **** enjoy Internet software, network acceleration software and other settings are reasonable, improperly set up the same will affect the user's use. C: non-running software and other files do not put into the running disk or desktop; open some software on the drop phenomenon, uninstall the software. D: usually on the computer (including auxiliary) equipment to strengthen the monitoring operation and maintenance, to do: equipment clean, well ventilated, connected to the contact resistance as small as possible, moderate temperature and humidity, excellent insulation, wiring neat and beautiful. Is the wiring: strong and weak signal lines separate? High and low frequency lines are separated? Eliminate all the wires bundled together in the alignment! Fourth: link good: check the host and the auxiliary keyboard, mouse, speakers, (Category 5 line) network cable R45 connector, grounding line, power supply multi-plug board, power cord and so on must be (contact resistance in Ω) good, check the household line connectors, telephone line plugs and so on whether the contact (Ω) is reliable, in order to reduce the failure of the machine line; cabling: vertical and horizontal, clear and neat (shall not be entangled). Whether the equipment plug-in contact is good, whether the memory stick is loose and so on. Fifth: the appropriate level of reception and strict impedance matching (wireless network card is: receiving field strength, optical fiber is: receiving optical power level): the link point signal can not signal is too large, nor can the signal is too small; signal is too large, the pre-circuit saturation, the signal is too small, resulting in a low signal-to-impedance ratio; impedance mismatch will lead to reflective attenuation, and then the signal is strong, it can not work properly. Six: the greater the better out-of-band isolation, the smaller the better in-band attenuation: xDSL, broadband, wireless, fiber optic and other users, are to provide the minimum in-band attenuation (less than 1dB), out-of-band isolation (greater than 60dB or more). The signal-to-hybrid ratio should also be greater than 60dB or more. ★ Copyright: This answer for the "harmony" original, no one shall steal! ★ As long as you carefully in accordance with the above to do, and keep often do, your equipment work smoothly, your mood is comfortable; configuration of the computer is not high, but also can make you very satisfied; otherwise: the configuration of the computer will be the same as the high failure, accidents occur frequently; like people wearing clothes (skit: good people and bad people in the Pace Chen: you give him even better clothes, he can not be on the grade!) Like people wearing clothes (Chen Pesi in the skit: good guy and bad guy: if you give him good clothes, he won't be able to go up to the top grade! No matter how high you are configured, if you do not follow the computer safety maintenance and use methods to use, you will fail constantly, accidents happen frequently. Many of the failures are man-made, things in people! ★ Copyright: This answer for the "harmony" original, no one shall steal! ★ Don't forget to adopt my answer! I'm not sure if you're going to be able to do that! I'm not sure if you're going to be able to do that.
