That isn't the issue. You stated there was a burning smell.
I didn't say your other hardware was ruined. You asked what could happen. If the computer is still working then there is probably no damage yet.
I don't know how things work in India but in the USA you contact the vendor and request a replacement. They give you a Return Merchandise Authorization (RMA). You return the item and they ship you a new one.
