I have my answer. After researching this problem it all boils down to a faulty electrlytic cap electrolyte formula that was used for industrial espionage about 10 yrs ago in the Taiwan area. Seems most computer faults can be traced to this problem and problems continue to crop up EVERYWHERE in the world to this day!
^read this http://en.wikipedia.org/wiki/Capacitor_plague You still see these capacitors to this date, mostly in cheap PSU's and motherboards. It has to be said that there are other causes for exploding caps. like if the circuit is poorly designed and there is excess current/ripple/voltage/heat going through the capacitor. Also if your power supply is poop and putting out of spec voltage to the motherboard, the caps wont likely last as long.
There was a problem with faulty capacitors being supplied to many manufactures a few years ago which continues to be a problem even to this day. One of the biggest contributing factors as to how long the capacitors last for is their ambient operating temperature. If you are having a recurring problem with faulty capacitors I would suggest that you look at the air flow over the graphics card. I don’t think that the power supply is to blame here as the capacitors on the motherboard have not failed.
