Troubleshooting Power Supplies - Troubleshooting on Computer and solutions

Power Supply is a computer hardware that serves to transform AC current into DC and the supply voltage to the computer such as: morherboard, hard disk, CD ROOM and others. Power supply voltage source computer is the most important, so that if the power supply having problems, then sem; ua computer components will also experience problems that cause the computer can not be turned on or off.
Here is a problem that often occurs in the power supply:

1. Computer suddenly died and lived again (restart) when the system is working. 
2. hard drives and cooling fans do not want to spin
3. Power On or system start-up failure 
4. The computer system completely dead

Diagnosis of the problem:

1. The power supply voltage decreases so do not mencukuoi for distribution to all components of the computer hardware. 
2. Problems on the ON / OFF switch on power supply
    
3. The power cable that connects the power supply from the power supply is damaged
    
4. The fan on the power supply was damaged so it does not spin that cause excessive heat in the power supply.

solution:

• Check the voltage source whose mother, or if necessary at stavolt to stabilize the power supply voltage 
• Check the power cord or try to replace it with another power cord. 
• If the power supply fan is not spinning, replace with a new fan 
• Check the switch ON / OFF switch on the rear of the power supply
•  Replace the power supply that fits the needs of your computer hardware, because each power supply has certain limits.
