Hi there, my name is***** hate to be the bearer of bad news, but I think you bought the wrong card. Windows 10 is not listed as a supported operating system for this particular card (which is now discontinued by the manufacturer), and I don't think there are any drivers for Windows 10. The operating systems it supports are: Windows 2000/XP/Server 2003/Vista/Server 2008/7/Server 2008 R2/8/Server 2012/8.1/Server 2012 R2 32/64 bit.
It looks like the IOCrest cards support Windows 10 and might be in the same price range, and the reviews are pretty good on Amazon. The 2-port card is $17.89. Have a look here. A recent review said the reviewer had no problems installing on Windows 10.
