Bluetooth connectivity problem

Hello,
I have a lenovo G50, and I have been having some glitches in my Bluetooth connectivity, I recently tried fixing it and found that my Bluetooth wireless driver thing was missing from my device manager under Bluetooth...the ones that are there are
1) generic Bluetooth Adapter
2) Microsoft Bluetooth Enumerator
3 Microsoft Bluetooth LE Enumerator
I have tried updating and fixing going through all video and third party help cites but non of them are actually helping.
If anyone knows how to fix this please help me out
