I just recently purchase a HP pavilion P6750z computer with Win7 OS. I'm trying to install a wireless D-Link DWA-556 PCIe adapter card. The card installs very easily into a PCIe slot. However when I boot the computer after installing the card, I get the windows blue screen. If I remove the D-Link card and reboot, everything is working just fine. I believe I am having a driver problem (not sure) because I did find on the D-Link support site something about using an Atheros driver. My question is, if I can find the correct Atheros driver, how do I install the driver and get it to work with the D-Link adapter when I can't get a clean boot with the adapter card installed? Any help will be appreciated. Thanks
