My computer is SONY CS19. It has been working well with Windows 8 operating system since its installation on it. But last evening, there was a problem that struck me a lot! When I use the video chatting with my friends, I got a black screen and it indicated me that the bluetooth video service is out of service. In addition, I have downloaded the bluetooth driver. And it seems to be no use.
Pls give me some suggestions!
Thank you very much!
