So it's definitely not the capacitors. I think the sound of dead > capacitors would be more like AC hum. The only time caps in a computer would give you ac hum problems would be if the main PSU ones were faulty, and then I think you'd quickly find all sorts of much more serious problems! Also, it may not be *those* capacitors, but it could very well still be capacitor related. A *well* designed mobo has them dotted all over the place, seemingly redundant and in parallel. There are also additional ground plane 'capacitors' formed in the very structure of the board itself. Personally I've not had very good results with VIA mobo's - all sorts of obscure problems, especially with the micro and nano boards. Now if the card's filtering is not 100% and the mobo's isn't either that could be the cause of your problems. > Might it be a PCI interrupt priority issue?
