So I recently got a Gigabyte R9 270x. I went to the AMD site and downloaded the correct AMD catalyst driver installer thing. Apparently it didn't recognize my card. I went into the device control panel and it isn't there. However, everything is plugged in correctly, the fans on the card are spinning, I have a 750 watt PSU, and I went into bios and my Asrock Extreme 4 says that the PCI-E slot has the card in it and bios properly recognizes it. This leads me to believe it is Vista's fault. I have uninstalled the AMD software numerous times and re installed it.
