Okay, here goes.

1) Im not sure

2) I'm not sure about current generation, but I know that there was a massive shipment of faulty capacitors a few years back. supposedly one company stole another company's capacitor plans and used them, which turned out to be faulty(but by this time millions had been shipped) and in this case, I'd say it wouldn't be your fault. However apart from that my assumption is a power surge, overheating or just wear and tear on the capacitor.

3) I doubt it would have damaged anything else, but there's always a possibility.

You can fix these, but I wouldn't recommend it unless you were well experienced with capacitor repairs, otherwise you could screw it up more(if its possible.)

If you have any queries about getting a new card feel free to ask, just list your full computer specifications and your price-range.
