Business Notebooks

Hello,

I have a problem with my sound card drivers or something else which I could not figure out. I am using this company owned notebook in my office. IT responsibles could not figure it out also.

Here is the thing, I had the audio couple of days ago. While listening the music I have paused the media player and did some other stuff for a couple of minutes. When I start a video or music file audio was gone. After restarting the pc audio was back online and samething happened again after couple of minutes. And then the audio is gone forever because restarting does not solve the problem anymore and now I see a cross sign on the audio symbol on the task bar. The error code on the audio symbol is "there is no audio device installed" but i ahve already installed latest conexant audio driver.  Additionally there is an exclamation mark in the device manager for "intel smart sound technology audio controller". The error code for intel smart sound technology is "Due to a problem windows stopped this device. 43"

I am fighthing this problem for a week. I have tried a lot of things to solve the problem but could not success.

1) I had uninstalled driver, restarted computer and installed latest conexant driver.

2) I have formatted the whole operating system directly using windows 10 usb. And updated all the drivers including chipset and audio but the error has come again. And I cannot use the sound, my problem keeps staying alive.

I appreciate any help
