Are you wondering whether your board has the bad capacitor plague? Here are some things to look for on your board that are tell-tale signs of bad capacitors. The board in the following photo's is an Abit KT7 Athlon motherboard. This particular board is a rather bad one, yours may not look quite as nasty..

Ok, from looking at those photo's, I'm sure you get the idea. Look for swelling on the tops of the caps, and also along the base of the caps. Take note of the brownish crap oozing from the bases, that is electrolyte . In some cases, you may also catch a whiff of a strange odor permeating the room, and this time it wasn't those refried beans you had for lunch. The smell kinda reminded me of an ammonia-like smell. Whatever it may smell like to you, the aroma is very distinctive!!
You may also notice that the capacitor isn't sitting flush to the board. If they're tilted and pointing in every which direction, that is not normal. The bases of good capacitors will be sitting flush to the board, and the cap should be at a near perfect 90 degree angle (perpendicular) to the actual PCB (Printed Circuit Board). Like I mentioned above, this particular board is one of the worst case scenario's... Beware that not all capacitors will bulge, swell, and burst. They can fail and you would never know by looking at them.
