The Troubleshooting Methods to Computer Auto Restart Fault-2

B, the hardware
1. Mains voltage is unstable
General home computer switching power supply operating voltage range of 170V-240V, when the mains voltage is lower than 170V, the computer will automatically reboot or shut down. Because the mains voltage fluctuations sometimes we do not feel, so it will mistakenly believe that an automatic restart of the computer somehow.
Solution: For a regular supply unstable region, we can purchase UPS power supply or 130-260V switching power supply to ensure a wide computer stability.
2. Insert row or the power outlet of poor quality, poor contact
Row of the majority of the market poor quality power supply plug, the internal contacts are based on hand-welding, and often use acid flux, so easily lead to the use of solder joints in subsequent oxidation caused by circuit or FireWire and zero leakage between the lines. Because hand-welding, and using of phosphorus brass sheet flexibility is poor, does not take very long it is easy to lose elasticity, resulting in the host or monitor power plug and have a greater access to poor contact resistance, in the long hours of work will be fever caused by a large number of virtual access, then it will show as the host to re-start or display black screen flashes.
It is also possible the wall socket we are using at home, most installation of wall outlet are not professionals, so the internal wiring socket is very non-standard, especially since their sockets, if we often use high-powered heater it is easy to lead to internal heating oxide formed virtual access intermittent power outages, causing the computer to restart or monitor blink phenomenon.
Solution:
① Do not buy inexpensive power strip that have poor quality power supply as to save money, buy some brand-name power supply plug row, because of its internal machines are installed automatically crimping, no use of hand-welding.
② For whether it is within the virtual wall outlet to pass on, we can host for a wall outlet to try and to see whether there is the same issue of the automatic restart.
3. The computer power supply inadequate or poor performance
This situation is also more common, especially when we adds a new device, such as high-end graphics cards,burner,hard drive, it can easily occur. When the master working at full speed, such as running large-scale 3D games, high-speed recording or preparing to read CD-ROM, just boot, dual hard drives read and write data, it may be due to the instantaneous power caused by insufficient power supply protection to stop exporting, but because the power stop the output, the load reduced, then the power start again. Since the recovery time is very short, so the performance is the host automatically restart.
In another case,the host switching power supply performance is poor, although the voltage is stable within the allowable range are normal, but because the output power in the harmonics with excessive, can lead to a regular hang or restart. In this case we can use the multimeter to test their voltage, the best way is to replace a superior power to replace the rule.
Solution: replace the high-quality high-powered computer power.
4. Host switching power supply electricity plug loose, being exposed, there is no plug tight
This situation, the majority will appear in the DIY machine, the host power cord not has 3C certification, and is not complete with the power outlet. When we shake the table, or touch the host, the host will automatically restart, General will be accompanied by a slight “pops” sound.
Solution: replace the high-quality 3C certification power cord.
