the computer im workin on kept resetting randomly ( normally before it fully booted to any operating system) upon inspection several capacitors near the cpu are swollen and leaking and im struggling to find the exact match to replace them, could i use a 560uf 4v instead of a 680uf 4v, there are a total of 4 that need replacing and a few others which i have the correct values for, im thinking this was caused by a power supply failure giving out the wrong voltage or something, i would replace the board if i could find one with the same chipset as there is too many programs to transfer to justufy a complete rebuild. thanks in advance.

We used to run into this issue on a specific series of Asus motherboards. Our in-house tech would replace all the blown caps with the same size ones to repair and the M/B would be good for another few years. If you cannot find a local electronics supply house that has the right size caps, you can try putting in the ones you have on-hand, but they would be more sensitive to blowing out than the previous ones were, and would likely not last as long.

thanks orcaknight for your advise i'll give it a go if i cannot find the same value, as long as it wont blow the cpu or anything if i cant find the same i may as well try them and keep my eyes open for a mobo with the same chipset and replace the whole lot when i do find one, its a shame they use cheap componants on motherboards because its only about 3 yrs old and set right for the office now and having to go through a full rebuild is a tediouis task in itself, and one day hopefully windows will support full upgrades without having to reinstall everything.
