AzimJaved: Thank you very much for joining the Intel® Graphics communities and for providing those files. We are sorry to hear that the PC is not working properly.
In regard to your question, the problem does not seem to be related to the audio driver, however we always recommend to install them manually from Gigabyte’s web site since they are the manufacturer of the board and the drivers were customized by them to work with your platform. The link below shows all the drivers for your board, and it says that the proper graphics driver version for your system is 4550, please try that one and also look for the audio driver in there:
You mentioned the problem gets fixed when installing graphics driver 15.46.02.4729, so as an option we can try to roll the driver back and stop the Windows updates:
If the problem persists after that, please provide the information requested on the link below, there is no need to attached the files that you already gave us:
