When replacing a capacitor, it must have an equal or higher rated voltage. The capacitance doesn't matter that much, if the capacitors are connected in parallel (which they most certainly will be, as they are used for power filtering), the sum of the capacitance of the new caps [in a certain area on the M/B, e.g. near the CPU] should be more than or equal to the sum of the old caps. EG on my board, there were 5 3300uF 6.3 volt caps near the CPU socket. I went to Jaycar Electronics, but they only had 10v ones. They had 10v 2200pF ones at the same diameter, and 4700uF ones at a larger diameter. So I put in three 2200uF ones and two 4700uF ones (a bit difficult to fit, but hey...). The total sum of the new capacitance is about 16000pF as opposed to 16500uF or so, which in reality makes no difference as electrolytic caps usually have a capacitance tolerance of +/- 20% or so and are expected to drop in capacitance about 50% over their working lifetime. I would just say unsolder the caps you can't read the values for. If my memory serves me correctly, on my board there were 5 3300uF 6.3v caps near the CPU socket, and about 8 1000uF 6.3 volt caps scattered around the rest of the m/b. Any more Qs just ask Cheers	forrest44 (754)
