Return that card to newegg and get the card that I recommended. I don't know what the rest of your system looks like but I can verify that it works quite well on Intel 6 and 7 series chipsets (although it did have some problems on my old P45 but that could have been due to PSU noise and shitty grounding on the case)
I'm assuming you can see my computer specs, if not, I listed below.
Corsair CX430 PSU
Asus Xonar DG 5.1 Sound Card
AMD Phenom Quad-Core 9550
NVidia Geforce GTS 250
I would return it, but I'm afraid the shipping would cost more than the card itself and they wouldn't be able to take it because I did a rebate on it.
