How to overcome the PC does not turn on: Failure Source?

When you turn on your computer, and even often look to solve this problem you should seek the help of someone. In this issue, you do not know how to handle it. Below I will explain and you have to  attention.you will know the operation of the power supply and the proper way to find and fix the various problems that may occur with this.

The main function of the power supply is to convert the energy from the wall outlet (AC) in the wall of what is used by the different circuits of the computer (DC), thus ensuring a stable power supply for the different components of the computer is working properly. Ie convert 110-120 Volt / 230 Volt depending on the country, +5, +12 and 3.3 Volt uses different components of a PC.

Besides supplying to supply the energy needed for the PC to work normally, also make sure that it does not operate if the power is inadequate, that our PC will not start until all of the appropriate level of energy that comes with the computer to work properly.

Among the main components involved in this process of rectification current are: input rectifier circuit, which reduces stress and improved from the power grid and smoothing circuit that prevents changes in the value of different line voltage input to affect multiple components receive power from a power source, also integrated comparator that returns the voltage required to change the circuit.

So if some components of the power supply is not working properly, my  team also affect the normal operation.

Tension that gives strength to make it through three connectors: Yellow to 12v +, red connector + 5V and 3.3V + orange connector, and the black wire is the earth or ground to close the circuit.

Knowing this we know then that when the computer is not on, and I have verified that the outlet comes out right, then you have to check the operation of the power supply to make it and follow the steps below I mentioned:

•  Find the power button on the PC and check the status of the connection, ie accidental cut or disconnected.

• Check the ignition key goes into the motherboard is also located on the premises If you have some experience as well, you can measure the continuity of the cable to the power button simply unplug, put the multimeter function continuity, placing the tip of the tester multimeter on each end, if the cable does not jeopardize present then read the tester should show values ​​close to zero, if not, if the cable has an error, then the value of the tester presented indicate that no current flows through the wire.

• If the power cord is in good condition, will need to check the current resource checking this fuse is not burned, for this you must disconnect electrical equipment, remove the power source from your computer, open it and check the fuse to see if the fuse is blown, if so it must be replaced by one of the identical characteristics and voltage.

You can perform another procedure as a measure of the voltage generating resources, and thus see if it works well or not, but this process will be discussed in more detail later.

Finally, I suggest you do the cleaning on a regular basis from the power supply, the acquisition of this dust which may cause undesired operation to do just enough to expose and clean the fan blades with a soft brush or use a blower to remove powder respectively.

It is a must have tool for detecting whether the cause of the problem when the PC is not the source of the power switch, so I suggest you take steps when presented with this type of problem on your computer and you can rule the same that it was a fault with the power supply, and why not able to solve alone.
