Hi rajith100100,
For Bluetooth issue, please ensure that the device you are trying to connect to computer is discoverable in Bluetooth settings i.e. both computer and the other device should be discoverable in settings.
It appears that a few drivers are missing from your system. You may refer to the article Here for correct order of installing drivers. You may download the drivers from Here -> Enter the service tag of your system -> Select the operating system -> Install/update the required drivers
Hope this helps. Please reply with the findings.
