weird problem

ok today i change my nvidia chipset 400 fan(the fan cooling it). i have nf7-s v 2.0. anyways i replace it with a zalman nb47j. you know some cases have front connections for speaker and mic? but they have cables u have to connect to the back of the case into the motherboard audio and mic.. when i was done connectin everything i turn the switch on the back of the case and usually u see a red light on the mobo turn on..right? well not on mine. mine just barely turns on and cant turn on my computer. but when i disconnected the mic cable the red light turns on and i can turn my computer on, but if i plug it in it it wont turn on, it kinda looses power or something.

(hope u understand my writing my english is not my language thanks you)

 

Your english is fine, don't worry about it, sometimes I hope everyone will pardon my spelling.

The only thing I can think of is to make sure the audio and mic wires are on the right pins, them little connections are sometimes hard to see.
