I don't know why you might be experiencing your problems, but I ordered this card when I bought my new Dell: Amazon.com . It has been in use for about a year, and I run 3 external USB 3.0 drives from it, and so far, so good. Warning, it does not provide power to devices, only good for data. I hope that helps.
