Here's the basic story: I had a D-Link Air Plus G510 on my pc and recently it died. I had an Azio AWD154B wifi card laying around so I stuck that in my PC. It was working fine for a while but now I have a Code 12 in device manager on this card. If I disable the card, device manager locks up, same with enabling it (after restarting my computer...). I updated the drivers to 22.214.171.124 from 1.5.4 and the problem still persists. Searches show that 2 or more of my devices are conflicting with each other. Here's my extra hardware pieces: PNY GeForce GTX 550TI Azio WiFi card Creative Soundblaster Live! CTX4760 sound card this PC is running Windows 7 Professional 64-bit. At this point I'm out of ideas. What else can I try?
