Old capacitors often fail and can be noticed because they "leak". You can inspect the mother board carefully to see if you notice any leakage around the capacitors. Capacitors that tend to lead look like very small cans with two wires holding them off the board.

Because they have leaked does not necessarily mean they are totally not functioning. Often life of the components can be extended by removing the mother board and washing it thourghly. A cycle through the dishwasher with plain water is said to do an excellent job. Make sure it is dry before you reassemble the computer to see if cleaning worked.

From what I have read you can just go ahead and wash it, but if I were looking at doing it, I would probably research the matter again. I do not think there is anything on a motherboard that is susceptible to water damage. At least not when it is removed and not powered.

Please keep up posted about what you do and how it turns out.

It looks like a white residue under some of the caps. I found a source for them so i may replace them. Component level repair wow! not bad for a ME
