do you have another psu you could try your system with?
what was your psu?
sorry it blew up! it was fun probably though!
There's no sound more sickening than the sound of a component crackling as sparks fly out of it.
I feel for you fellow slayer. To answer your question, the best way to see if the other components are working is to stick another PSU in the case and hook the components up. It sounds like that's not an option for you. If you have another PC, you can check components other than the motherboard and CPU by connecting them to your other PC. To be fair, if you have access to another PC you could just grab the PSU from that provided it's powerful enough to supply your system.
