about 15 minutes ago, my cpu exploded. what has been affected? motherboard? psu? cpu cooler?
my cpu temp was 80 degrees at the time  i changed the voltage from 230v to 115v hoping that the power would lower the performance and KABOOM.
please help!
what parts can be reused? |

It's a joke?
Sorry but if you have changed the voltage from 230V to 115V hardly something have survied it ..... |

hey.....o my god....
i think they changed the voltage of PSU from 230 to 115v..........

Did you change the voltage on the power supply while still feeding 240V into it? Ahhhhhh!!! Don't play with things if you don't understand what they do!!!!
At a bare minimum your power supply is stuffed. Worst case is you have destroyed everything else as well. Change the power supply first, don't play with the setting and then go through each component until the system works again.

115V is only for US users if you live somewhere else then you have voltage in electric socket at 230V. You made overvoltage by 100%. In 99% you have burned all components - I'm sorry. I had bad experience when my electric power station gave me 400V for a second. Only big grey smoke from PC and all components where ready to throw to waste bin.

| so in the US, voltage would double to 230v which means increasing double of its own voltage. i live in the UK and i 'decreased' the voltage from 230v to 115v.. would this still have the same effect? |

A friend of mine done such a thing not long ago.
He burned the PSU and a part of the motherboard (build-in sound card).
Fortunately I was able to fix the damage by replacing the PSU and adding a PCI sound card.

IMHO you didn't understand how a power supply unit works.
If you get 230 V from your power outlet you MUST put the switch on your PSU in the "230 V" position. If the PSU is used in the USA - where you get 115V from the outlet - the switch must be turned in "115 V" position.
If you turn the switch in a wrong position you will get problems - because the PSU will get a "wrong type" of electricity! Not only the voltage will be wrong but also the AC - frequency. In the USA 60 Hz frequency is used. In Europe we have 50 Hz AC - power frequency.
Just imagine you have a car with diesel engine and you fuel it with gasoline. What will happen?
Here is an link to a Wikipedia article about electricity.
