No sign of Bluetooth or Wifi following hard drive replacement and new OS loaded

Hi Everyone,

Following a new HDD & install of the OS my Dell 1525 is not showing wifi or bluetooth and is not letting me connect via wireless. I have tried installing drivers but nothing. I can only connect via ethernet.

I also tried removing the card and replacing it to ensure it was in correctly but still nothing. The set up menu on boot shows wireless card present and all enabled to factory defaults.

This is driving me insane to say the least and have tried everything I can think of and find.

Can anyone please, please help!!
