On any motherboard or other component of a PC running a plurality of capacitors and if fails even one of them, the computer may stop working. Here are a few recommendations, how to determine idle members.
What exactly is broken?
they, who rarely have to deal with your own or someone else's computer, in most cases, notice the damage to the capacitor only in the event, when it stops working. If we are talking about the individual components of the PC, they, usually, released or shall repair the masters.
Most often defective components due to a failed capacitor devices are power supplies. Причем могут использоваться для подключения разных устройств — монитора, system unit or router. Also, these elements fade on motherboards or graphics cards. Of course, best solution in this case - buy capacitors and replace them, but should first identify the defective.
Symptoms
Since most such damage appear on rather old devices (that more than three years), first of all you should check all capacitors for malfunctions. There are several signs, allows it:
- computer does not start. In this case, check all the items, including the power supply, motherboard and other components. This is one of the most frequent cases, and here there is a high probability, that other devices have been damaged because of the capacitors;
- inclusion occurs late. Quite often, the power supply, where capacitors were damaged, supply voltage to the computer with a delay. It is often possible to see the situation, when the PC is started without any problems. This situation occurs periodically and is a sign of the need for repair;
- typical squeaks. Since not all broken capacitors make the computer inoperative, but each of them after the failure of the can “squeak”. The advantage of such a feature - instant diagnosis;
- the device becomes unstable. In practice, this is determined by the sudden hang-up or restart the computer even with a freshly installed OS. This may indicate a possible power failure due to a broken capacitor;
- unpleasant smell. Often arises related to overheating, malnutrition and electrolyte evaporation.
As can be seen, signs of when to carry out the replacement capacitors enough. So in many cases, repairs can be performed independently, in fact replace the capacitor is not so difficult.
