Hmm. You know I usally just clean my hard drives with magnets and then give them a good salt water bath. Then I dry em in my microwave, and I assumed that would work with mobos. I guess now that I think about it, putting sensitive electrical componets in the microwave isn't a good idea.DONT USE THE MICROWAVE!!!! I have never tried that myself, but that sounds like cooked on dust to me. I would try using a can of compressed air or something of the sort for your first time, or until someone shows you how to properly clean it. If I was you I would try on an old board first, just to get the hang of it.
