Sounds like a mobo bluetooth. You could try downloading newer drivers for it and see if that helps.
I myself have had issues using internal bluetooth for gaming controllers. I used an external one that is verified to be 2.0+ compatible and it works just fine. If it is not 2.0 or higher, it will not work with PS controllers.
I have a video on using it with SCP. But I have since then stopped using SCP and just connect the PS controller directly to dongle from Windows bluetooth screen. Works fine.
If you are curious of the video, you can watch it here.
