|Is the AC voltage in India the same as in Hong Kong?|
If it is not, there is a slide switch on the back of most PSs - you must move it all the way to one side so it shows the proper voltage.
Shipping a computer exposes it to possible physical jostling, which can loosen things.
You could try unplugging the case and opening up the computer case and making sure all connections are fully seated on their pins and in their sockets, and the ram and cards all all the way down in their slots.
"After a while the fuse for the room went off."
My brother had one PS that failed simply because of a circuit breaker tripping off in his own home.
Some non North American computers have a fuse in the power cord itself, but if that has blown the computer would not come on at all.
If you can temporarily borrow a used PS from a working computer to try, that will confirm whether the problem is because of the power supply.
