OCZ Mod XStream PSU // PROBLEM

[Nitrojan]

I have the OCZ Mod XStream PSU in use with a Maximus Formula motherboard.. Whenever I try and turn the mobo on, Most of the LED's flash once and then turn off.. I then turn the PSU off at the back and can still hear a constant buzzing sound.

Is this a sign to RMA it? Or is this normal.. I'm trying to figure out why my mobo keeps cutting out.

Isnt that dangerous? Sticking a paperclip into a 900w 24 pin connector and firing it up? o.O

edit: ok I jump started it.. all my fans are spinning except PSU fan.. PSU fan leds are not lit also..

I can see the PSU fan trying to spin.. it moves to and fro like half a cm.

EDIT 2: Ok.. so after a minute or so of trying to spin.. it's now spinning.. not the fastest Ive ever seen a fan spin but still.. The LEDs are also still unlit..

Ahh yeah I tried it.. there are no LEDs on the fan.. and all the onboard fans spin and light up correctly..
