If the power supply has blown two fuses, then it is almost certainly faulty power supply. A shorted component in the supply is causing the supply to try to draw more current (from the wall outlet) than it should safely do; the fuses are blowing because of this, because that is their job- to protect the rest of the system from electrical overload.
As djrivera1 suggested, do not continue trying to use the computer, as you risk further damage by doing so. The supply can be tested at a professional computer repair shop if you want the definitive answer as to its condition, but from your description I'd say she's toast. Hopefully, the fuses blew quickly enough that other components in the computer escaped harm, but don't be surprised if that's not the case. :(

Try different cable. The one you're using could have shortened the circuit.
If so, it would be visible in a form of burned or melted insulation.(also, no power ever came to the pc thus leaving it untouched)
Bare in mind that it is a fire hazard.

I agree with what Rik said. You can start a new thread in the same forum, but please don't post in old thread especially in a 5 years old thread.
