Hello everyone, this is my first post here so sorry if I ramble! I recently bought a used alienware 17 R3 which came with windows 10. I'm not a fan of win 10 so I installed win 8.1 instead, all the drivers went on fine but the Bluetooth adapter is showing error 43 its been stopped by windows. I have looked for answers, but found none that work. I have tried uninstalling and reinstalling the driver but no luck. I would go to the manufacturers site and download their driver but in device manager the adapter just says "generic Bluetooth adapter". I can't seem to find a Bluetooth driver on the dell site either. Out of ideas on this and need some help please folks.
