For the first time in six years, I opened my computer case to clean away the dust. There's so much dust in the PSU fan, I had it to unscrew the PSU to clean it. Two of the capacitors in my power supply unit have leaked, a couple more are bulging, and yet the computer is still working fine. I don't game anymore, just browse & watch movies, but I intend to have this power supply replaced ASAP in order not to risk the capacitors bursting and whatnot.
My Gigabyte motherboard is also 6 years old. The capacitors look like this: http://www.gigabyte.com/microsite/111/t ... erview.htm
It's solid polymer capacitors, the same kind that most good motherboards use these days. Because these capacitors don't use electrolyte, it is said to be immune to leakage/bursting. And yet, I understand that nothing lasts forever, and these capacitors only have a longer lifetime than the typical electrolyte capacitor. So, if my motherboard capacitors still look as good as new, with no visible sign of leakage or bursting, how do I know whether it's still okay or not?
