Hrmm... well, I had this problem... and since I've been dealing with music production and computers for years I was quite ashamed to realize that I had connected the data cable between the PCI card and front panel, but NOT the power cable. A problem that was pointed out in another thread.
So - after laughing at such stupidity I opened my computer only to see that I had forgotten to connect that very cable myself.
Hope you're smarter than me..
