Just had fire on a friends PC
friend told his pc couldn't start
I checked the power supply -> no power
I placed the thing back in the pc cause the friend wanted to go to the shop where the pc came from to repair the thing.

the friend insisted to try it one more time:
result:

real flames and smoke out of the transfo!

no LOL, I hope the other parts are still OK
what do you guys and girls think?
