Analyse the reason of computer automatic barrier machine

1, according
Normally, voltage scope170 V-240 V, when city170 V, computer will be started voluntarily again or barrier machine. Because according to news from city, we can't feel the fluctuation of voltage sometimes, so, will think accidentally that computer is baffled and voluntarily heavy to have started.
Solution method: For theUPSPower130-260 VThe switch power source
銆€銆€2, insert row or the
It is good that the power source on business inserts row most quality, built-in contact is to adopt acidity and frequently with handwork welding to help welding flux , so causes to weld oxidize in the following use to arouse broken road or battle line easily and between zero line leakage of electricity. Because handwork is welded , at the same time because of adoption Lin brass flat flexible difference, can not use how long lose elasticity easily, cause contact the bad contact resistance with greater arising with the plug of power source of host computer or display, when working for a long time, will give out heat in large quantities and cause to be empty to receive , it is that host computer starts again to show now or display dark screen twinkles.
A possibility is the wall socket used in our home, the installation of the most wall socket is not to use professional , so the built-in wiring of socket very not standard, especially these sockets if we often use big power news warm ware causes inside to give out heat very easily oxidize is empty to receive form intermittentance break news, arousing computer weight start or display blinks phenomenon.
Solution
銆€銆€ It is cheap to do not seek purchase price honest the row of power source of not thing America inserts , purchase some famous-brand power sources to insert row , because its inside is machine automatic installation crimp , have not welded with handwork.
As so Fou belong to the wall socket internal empty problem
3, the power of computer
This kind of condition is also common, is especially us after for own host computer have added new equipment, if have changed , it is high grade to show card , has increased CD writer, after having added hard disk, appear very easily. Pawn host computer to work at full speed , is large scale for example operation3DGame carries out high speed to carve record or is prepared to read to take compact disk , just start , two hard disks as Kao data, may arouse power source because the instant power of power source is insufficient to protect and stop output after, but stop output because of pawning power source, load is alleviated , now, power source starts again. Because it is very short to protect rear recovery with time, so giving our expression is the automatic weight of host computer starts.
There is still a kind of condition, it is the switch performance difference of host computer of power source, though voltage is stabilize also in normal limit, but in its export power source, harmonic content is too big, can also cause host computer to be regular to halt or start again. For this kind of condition when we test its voltage with universal meter, are normal, had better change a fine power source to carry out replacement remove.
Solution method: Now,
銆€銆€4, the switch electricity
This kind ofDIYOn machine, the power3CCertification does not be formed a complete set with the socket of power source. When we rock table or touch host computer, will arise the automatic weight of host computer to start , general return meeting companion has light news strike sparks"Pa"Sound.
Solution method:3CCertification
銆€銆€5, the powerATX20Socket has
This kind of fault is not commonATX20Needle plug, see whether20The built-in spring flat of the plug of power source of needle whether the phenomenon that has oxidize , this also causes contact resistance to be big very easily , has bad contact , arouses host computer to halt or value to start. Sometimes, need to still inspect20The jumper of needle
Solution
銆€銆€ Weld if being mainboard is empty to weld , directly mend with electric iron to weld may. Pay attention: When is for mainboard , hard disk , show the computer board cards such as card to weld , must will the good earthing of electric iron, or when welding , pull out the plug of power source.
If be the problem of power

銆€銆€7, memory
Memory bar goes up if certain chip notPOST), but when runing , it is big to give out heat because of memory to measure and cause function to become invalid and is unexpected and heavy to start. When storing damage in the most time, start can report to the police , but after damaging , memory does not report to the police , do not add news fault is still some. Had better use the France of removing , can determine fault position fast.
銆€銆€8, the
If the internal damage of CD driver, it is slow to also cause host computer to start or can not pass through self check , may be also to start suddenly again in working process. Have changed CD driver for a kind of rear condition if being us rear appearance, may be very much that difference arouses the power consumption of CD driver. What all need to know is that though CD driverATPIInterface is identical, but it is not identical that different manufacturer domestic it draws foot definition, if our line of hard disk has problem, may produce for certain a brand CD driver use no problem, but the condition of can not work for other brand CD drivers, this needs all to pay attention.

銆€銆€10, the card ofUSBWhen interface
This kind of condition general is becauseUSBEquipment breakdown as land short circuit, net card workmanship not standard etc., when we use these equipments, will because suddenly the short circuit of power source arouse computer weight to start.

If our host computer do to disturb performance difference or shielding is bad, will arise the unexpected phenomenon of host computer of starting or halting frequently again.
The problem that computer arises is very strange, but if we can know the basically working principle of computer, that we will be handy in removing the soft hardware fault of computer, will not day head margin is big. Hope that this text can help for all
