I'm sorry, what exactly did you change? Did you used the molex or not? When i read your writing is kinda confusing to understand.

One of the reasons can be that your risers are shorting. On that mobo they are very close and sometimes can touch and short each other. I use electrical tape to insulate them and have no problems.

1) not my first post here on the subject, kinda middle of discussion. Yes connected molex to the mb.
2) do you have any substance to the shorting claim? cause I'm yet to find one pair touching each other(though maybe its just good soldering), but the main point is: it seems that the biggest bumps are the ground.
