Did you have any surge protection devices hooked up or do you use a UPS?

Truth is to me it sounds like its fried. Smoke and popping noises are never a good sign.

It is never a good idea to mess with the voltage, You will need another power supply..
ANYTIME you smell smoke/Electrical smell it is always a good Idea to turn it OFF, Then replace... We don't like fires...
