Default Soldering caps

When attempting to repair a bad motherboard can you usually get away with only replacing just the capacitors that look or feel like they're bulging? Does that usually fix it?

Obviously it depends whether it was the caps that were causing the problem. If it was then yes that usually fixes it because caps that look good normally are.

I was always told to replace all caps of the same value as the blown ones even if they looked good.

That can be true. If you see like 3 bad caps which are all the same make and value then it makes sense to replace the rest of those since you obviously have a bad batch.

If upon visual inspection of the motherboard and the only damage you see is bad capacitors then you may "get away" with just replacing the bad capacitors, does this mean that the only thing gone bad is the capacitors if a motherboard won't work, no. The are lots of components on a motherboard, of any which could go bad. You could have a bad fuse, resistor, diode, etc. I've even had a south bridge catch on fire. Anything could go bad, but a good close look at the motherboard can most of the time reveal a bad component.
