It's my first post... 
Do you use risers? Are they with molex? How many cards are connected?
As far as I know if you connect a lot of cards to your MB you should use a riser with molex otherwise there is a chance that yours MB will be damaged. And IMO you can connect up to 5 card to a "standard" MB. I've read a lot of stories where 5th or 6th card didn't start even using riser w/ molex.
Happy new year!
