Yes, those were two unrelated problem, and, no, a capacitor won't blow, 
but as it degrades (due to excessive heat, bad quality or simply a 
borderline design), it will go on working while the equipment is 
switched on, but if you turn it off it won't work when you switch it 
back on.

Well, usually you don't have a choice on the components used, only on 
the final product, and the problem with bad capacitors in motherboards 
is spread among many top tier vendors, so it's not a problem of cheap 
components. Besides, there are no-name capacitors sold as brand name ones.
And even expensive products eventually fail.
