Identify - The System Errors & Symptoms
This is some functionality symptoms that your system will display if your PC capacitors are spoil. Please take note that these symptoms can occur even if your PC capacitors are not spoil.

System Faulty:
Often or Permanently Blue screen
Memory Test Failed even had replace the RAM card
Fail to Booting even had repair the OS

Stucked at half way during reinstalling OS
System randomly and frequently Hang up.  
I like to share with you how to fix the PC problem regarding bad capacitor. This step only can apply, after
you had check all OS and other device then finally you found that some of capacitor are swelling.
Refer the red arrow, you will realize the capacitor swelling.
Actually ,this is a basic repairing of capacitor replacement, no matter what is the MOBO type, if you are lucky. The MOBO will function back as normal condition.
 
You need the Tools:
1) Soldering Iron & Solder Lead
2) Soldering Sucker or Solder Wick
3) Desoldering machine

I am very sure that you know the Soldering Iron, but its better if you using the Desoldering machine to avoid
the MOBO copper track strip out.

This is the Desoldering machine to suck the remain solder Lead & to Soldering the replacement capacitor
This is the view after remove the bad capacitor .Firstly you need to ensure the capacitor pole , (+)positive & (-) Negative. Refer the red arrow.


The capacitor have only 2 pole , you can see the (-) by one side line with - mark, and don't solder it at wrong pole. it will not function or will become a fire cracker once you switch on the PC.


And you must replace with same voltage and value for the capacitor, eg: as above 6.3v 1500uF
