If the power supply meets the Intel ATX12V guidlines it should have turned
off and not be damaged. If it's a cheap/generic power supply then all
bets are off. The motherboard should be dead but most likely nothing
else.

okay... i used another PSU that i had... strangely it didn't work...
but then when i used another power cable (from mains to psu) with that
other PSU it worked... the machine ran perfectly, i formatted the HD,
installed windows... everything was fine and perfect... so i came to
the conclusion it was a 5a fuse on that cable that got damaged...

??? A "normal" AC power supply cable has no fuse in it at all, just a
straight pin-to-pin connection. If you have a multimeter you might check
the continuity, or rather, resistance of the conductors.


...till
i decided to test the other PSU with the working mains-psu power cable
('cos it was a good psu)... it didn't work, and not only that, but
when i tried to put back the working psu it didn't work either!...
eventhough i connected it with the working cable... now i'm gonna go
and buy some 5a fuses...

Normally a closed circuit short on a power supply will turn it off but not
blow the fuse, if you're meaning the internal fuse, not a ? (cord fuse).
Again this assumes it meets ATX12V guidlines, not missing essential safety
features.

It's curious that you're having this intermittent success... perhaps the
power supply or motherboard 4-pin connector is stress damaged or burnt,
making bad contact.


i don't know if this will work... this is strange... but i was
relieved and happy when the computer ran and i was able to run windows

That firecracker sound you reported is troubling, something is likely
damaged and ought to be isolated and repaired or replaced before the
system is powered up again. A fuse blowing makes little to no noise.
