Computer will not turn on ?

PC Not Reacting, When Power Button Pressed.
Problem: You press the power button to turn on your PC, but PC does not show signs of life. What happened?

Solution: If this happens on your PC, there are several possibilities that must be examined one by one gradually.


Step 1:  
Check all the electrical network, from the AC outlet to the PSU (power supply unit) on your PC. Is it installed perfectly. Starting from the PSU to make sure the switch in the ON position, or if you use a UPS (uniterruptable power supply) and / or stabilizer AVR (automated voltage regulator). Make sure all in the ON position and in a state to function properly.

Step 2: 
If it is not the cause, then the next new possibilities on your PC. Make sure all cables (especially power cables) and the components installed properly. The trick with mebuka casing, then squeeze back component and connector cables available. Sometimes this is because the connector is not connected properly. Note also ATX 12V, which can be found on most motherboards four years. Motherboard will not act, without ration power from this connector.

Step 3:  
It would be quite troublesome. Make a check of device one by one. The definition is a CPU and motherboard. Make sure both are still functioning properly. Because let's say if the CPU is damaged, the system will not light at all. Likewise, if the motherboard is damaged. Especially for the affairs of any power source (MOSFET, power lines on the PCB and so on). It will also cause the PC will not react at all.
