Another computer?

Well, my wife just told me that the computer that we sent back to the Philippines a few months ago just ate another power supply. I told my wife "What" ? I can't believe it this! We've had this computer for over 6 years and never had a problem with it. Then we send it to the Philippines and from day 1 they've had problems with the power supply. Now I'm thinking because the Philippines uses a different power rating than the U.S. I believe it's just too much. They have gone thru 2 power supplies since receiving this computer. I can't help but feel a little upset. Obviously something is wrong with their power over their because why do they keep popping power supplies? Maybe they don't have a clean power supply. I don't know.
